Fedora Networking :: Very Slow Firefox Performance

Dec 26, 2009

I have fedora 12 and since I started using firefox I noticed that it performs very slow. Slow when opening, when displaying information etc..I thought that there was something wrong with my wireless device but I installed opera and it works very fast. The strange thing is that before that I installed google chrome and also worked very slow for me.

Ubuntu :: Firefox Slow Performance In 11.04?

May 25, 2011

Just curious if anybody else had experienced Firefox being slightly sluggish in the new release of Ubuntu? I'm running 64-bit Ubuntu on a Dell laptop (Inspiron 1445) with a fresh install of Ubuntu 11.04 on it. I haven't touched or messed with any of the settings.

Ubuntu :: Slow Performance Of Mozilla Firefox In 10.10?

Nov 20, 2010

I would like to report an issue regarding Mozilla Firefox in ubuntu 10.10. Continuously, a slow performance is experienced whenever I am trying to browse through the web. It takes about 20 sec to load a page. This issue was always existed in my system even when I was using the previous version of Ubuntu, 10.04. Is there any solution about it?

Fedora Networking :: Wireless Connecting Fine But Slow Performance

Apr 29, 2010

My wireless was connecting fine, but it was impossible to browse with. So, after searching around for a while I found a thread where it said to enter this and reboot.
#echo "net.ipv4.tcp_moderate_rcvbuf=0" >> /etc/sysctl.conf
#echo "net.ipv4.tcp_default_win_scale=0" >> /etc/sysctl.conf
But after entering that and re booting, now I cant even connect to the wireless. It says connecting but times out.

Fedora :: Slow Performance After A Power Outage

Aug 7, 2010

My computer is running really slow after a power outage. It was fine, then the power went out. Now it's *unabably* slow. The OS takes a long time to load, the simple calculator takes a few minutes to show up, Firefox doesn't even load at all before I give up. And it won't shut down normally. I have to use the power button.

So did the power outage fry somthing on my PC. Do I have ot replace RAM or the processor? Or is it a software issue? Do I have to do something as drastic as a reimage?

OpenSUSE :: Overall Slow Performance Of 11.2?

Dec 22, 2009

First of all, apologies if this is not the correct place to post this. I recently installed openSUSE 11.2 (Gnome, 32bit) on my newish PC. It is an Acer Aspire X3200 (AMD Phenom X4 Quad-Core, 1.8 GHz, 4096 MB, NVIDIA GeForce 8200 Integrated, can provide detailed specifications if needed). I've to say I am very disappointed with the results so far! Sorry to say this but I'm having a whole load of problems that I never had when I had Vista or with current Win 7. Here are the issues:

1. Slow network performance. I've disabled ipv6 but it is still the same. Not only when I use Firefox, it is also slow when I use console based programs. 2. Instability - Gnome system monitor crashed 6 (or more) out of 10 times I use it. System Monitor users more CPU resources than anything else! Also when I started the PC this morning, I only had the desktop wallpaper. No icons, no taskbar, no mouse movements or menus, nothing. I had to force shut down it after a while. I'm sure we all are familiar with this on XP but I've never seen something like that on Linux!

3. Annoying noise coming every time I move mouse (mainly when scrolling) and even if I'm not doing anything. I suspect it is coming from my HDD indicator as it always blink even when nothing is running. This can't be a hardware issue as I've never had this on Vista or Win 7 (it is virtually silent on Vista and XP but not on SuSE) This noise is driving me totally mad.

4. Slow performance in general. No matter what I do, even typing this on this text window, it seems everything is running so slow. I never had this problem when I was running 10.x on my 6 year old PC. CPU is always running around 20%-30%, when I don't run any other applications but just Firefox (I have Foxclocks, Delicious and FEBE as add-ons and I don't have any problem using them on Vista or Win 7). I am using Compiz, not sure if this has got anything to do with that.

OpenSUSE :: 11.3 - OpenOffice Slow Performance (Need More Memory)

Oct 1, 2010

Ever since 11.3 Open Office was performing "badly" to say the least. It loaded slow, with a few documents open "save-as" and selecting a different folder took up to a minute and so on. Anyway I had the suspicion that there maybe not enough memory allocated. Nothing within the OO settings worked.

Then I looked into yast=>/etc/sysconfig=>System=>Limits...
found "HARDLOCKLIMIT" set to "@256"
changed to "@512"......OK finished.

Ran a test with 10 documents open
a) Startup was much faster
b) Saveas instantly
c) PDF instantly
d) Selecting new folder instantly
Preliminary conclusion : Java(sun) and OO needs more memory

OpenSUSE :: 11.4 Slow In Terms Of Speed / Performance

Jun 30, 2011

I'm new to openSUSE and my computer is quite slow although my computer isn't that bad. I opened up ksysguard and it appears that my CPU is the bottleneck. My CPU usage is usually 100%, then after a few seconds, it goes down to 20-60% and then it goes back up to 100% after another few seconds. It says I have 141 processes running (I don't know if that's normal or not).

My Specs are:
CPU: AMD Duron (tm) processor 1.8GHz
Graphics Card: NVIDIA GeForce 6200
Memory: 2GB RAM
I'm using KDE.

Ubuntu :: Extremely Slow Swap Performance

Jun 24, 2010

I'm getting horrible (unusable) performance every time swap is accessed. This was compounded by the GEMS leak and a few other memory leaks, but now under normal non-leaky memory usage swapping is still intolerable. For instance swapping out ~300mb when I opened a new program with RAM full resulted in the system nearly freezing up for about 3-5 minutes (however long it took to brew a cup of coffee and come back to the system just finally unfreezing).

Fedora :: Firefox Very Slow Page Loading

May 5, 2010

With the last several updates to Firefox, loading pages from several different sites slows down to (slower than) a crawl - taking sometimes minutes. Most of the time, this occurs loading ads.

I don't remember what release this started with, but I didn't have problems before, and I don't have any problems loading the same web pages on IE8 (running on XP). This is the same on F12 and F11.

I have tried changing some of the securty choices, even tried blocking certain sites, but no luck.

Also, several times after a download, firefox freezes, although the rest of the desktop is okay.

Debian Configuration :: Seeing Slow Network Performance With Large Mtu?

Apr 22, 2010

I have 2 ASUS Boxes (one with 8GB, one with 4GB) When both mtus are set at 7200, using scp to copy a 56MB file takes 2:06. If I reduce either mtu to 1500, the speed is 2 seconds. I'm wondering if this is some kind of kernel bug or driver bug or what. For the moment, I've lowered the mtu to 1500 to get the performance out of the machines, but find it interesting that what should make it faster is actually slowing down. Where should I post this to get it looked at? Is anyone else seeing it.I see a similar performance issue with smbclient too.

Ubuntu :: Very Slow Evolution Performance With POP3 Account

Apr 11, 2010

I first seriously tried to switch to Ubuntu. I now find myself very rarely booting into Windows XP, and all the apps I need to use have free replacements.However, after porting about 15-20 years worth of email from Outlook (via Thunderbird) into Evolution, I'm finding Evo's performance has gone down the toilet.It was snappy to start with, but over time has got slower. I regularly get long waits as it displays notes that it is retrieving message number <whatever>.

I'm using POP3/SMTP for most email (I've a low-usage IMAP account with gmx.com too), but it seems like some sort of issue where I'd want to optimise or "defragment" my local mail store.Has anyone any ideas or suggestions on this?My ~/.evolution/mail folder contains about 2.5Gb if that's any help.This is with 9.10 Ubuntu; I have done some basic tuning on the setup, but not a lot.

Ubuntu :: Power Manager Hangs - PC Slow Performance

May 13, 2010

When the pc is powered up it takes ages for the login screen to come up and after that it hangs then comes up with a power manager is not responding fault, when I get into the desktop it takes ages for the top bar to appear and I noticed that the wireless usb dongle takes ages to connect. USB hang at boot? I have recently installed a usb printer. Weirdly a reboot fixes the issue, it seems to be at times the very first boot up where the problem arises.

Server :: Very Slow Raid Performance / Only Write Speed

Jan 5, 2011

I have recently migrated my file server over to a HP Microserver. The server has two 1TB disks, in a software RAID-1 array, using MDADM. When I migrated simply moved the mirrored disks over, from the old server Ubuntu 9.10 (server) to the new one 10.04.1 (server).I Have recently noticed that write speed to the RAID array is *VERY* slow. In the order of 1-2MB/s order of magnitude (more info below). Now obviously this is not optimal performance to say the least. I have checked a few things, CPU utilisation is not abnormal (<5%) nor is memory / swap. When I took a disk out and rebuilt the array, with only one disk (tried both) performance was as to be expected (write speed >~70MB/s) The read speed seems to be unaffected however!

I'm tempted to think that there is something funny going on with the storage subsystem, as copying from the single disk to the array is slower than creating a file from /dev/zero to the array using DD..Either way I can't try the array in another computer right now, so I though I was ask to see if people have seen anything like this!At the moment I'm not sure if it is something strange to do with having simply chucked the mirrored array into the new server, perhaps a different version of MDADM? I'm wondering if it's worth backing up and starting from scratch! Anyhow this has really got me scratching my head, and its a bit of a pain! Any help here would be awesome, e-cookies at the ready! Cheers

Fedora :: Firefox Becomes Unusably Slow / Uses Excessive Memory

Nov 23, 2010

I'm using Firefox 3.6.12 on Fedora 14 (64 bit) and have noticed that after using it for a while (and/or leaving the browser open for hours at a time), it becomes almost unusably slow and uses an excessive amount of memory. For example, any of the following can cause Firefox to temporarily (for 5 to 10 seconds or so) stop responding:

- clicking on a link
- opening or closing a tab
- scrolling
It will always start responding again, sometimes after the window darkens (to indicate that it's not responding) but it's so bad that it can't really be used. Closing it and opening it (restoring the tabs) again fixes it for a while, but the problem recurs. Regarding the memory usage, it was using 850MB (according to System Monitor) when I closed it, and having re-opened it and restored the tabs, it's now using under 200MB (but appears to be rising).

Another way that this manifests itself is that when trying to watch a Flash video (like iPlayer), it pauses for a second every 30 seconds or so, making it very annoying to watch them (I've switched to Chrome for this now, and am tempted to switch for general browsing, but like the plugins in Firefox).Is anyone else having these issues, and does anyone have any suggestions on how to fix it?

Slackware :: Hardware - Performance Drop - Slow Screen Refresh

May 2, 2010

My system is (and was) Slackware 13 64bit I had DFI LanParty NF4 with AMD Athlon64, 2GB (dual channel) of RAM and Gigabyte GeForce 250 1GB. Now I have Asus P6X58D Premium with Intel i7 960, 6GB (triple) of RAM and the same graphics card + 3 internal SATA hard disks (no partitions change). I replaced hardware and noticed a performance drop.

In text console it looks like slow screen refresh. Also visible during boot when next line of text appears with a delay. I can even see as midnight commander blue window unfolds from the top of the screen when I start it. Switching from text to X takes more time. File copying takes more time. I have Xp guest in VmWare Workstation. Windows runs noticeably faster. I have reinstalled Slackware and changed (in BIOS) default IDE mode for SATA to AHCI. Still slower then with previous hardware. Maybe I am too oversensitive now, but I think moving around in BIOS is not smooth either.

Debian :: Game Performance - Impossible To Play - Open But Everything Is So Slow And Choppy

Feb 20, 2011

My last laptop was replaced (I gave it to my step-dad, his laptop broke and I bought myself a new one).

I am running Squeeze (as I was on my other laptop) and everything is fine except for the games. On my other laptop games like OpenArena and Warzone 2100 ran perfectly fine, but on this laptop, they are impossible to play. The game will open, but everything is so slow and choppy that it takes a couple of minutes to even move the cursor to the exit game buttons.

My current laptop is an HP ProBook4525s with the current specs:

AMD Athlon Dual-Core P340 2.2 GHz processor
2GB DDR3 RAM
ATI Mobility Radeon HD 4250 Graphics Card

I'm not sure what other information to put here, I've tried searching how to fix this and most people say to lower the resolution and details for the games but that doesn't work, heck, even Tux Kart is too slow to play!

When I installed squeeze I was informed that I didn't have the rtl8168d-2.fw firmware for my laptop, I'm not sure if that helps here at all (can't seem to find what it is for, the only things that google gives me are very technical with fixes that involve re-compiling the kernel).

Ubuntu Servers :: Slow Performance On File Server (LVM/ReiserFS/SoftwareRAID)?

Aug 18, 2011

It stores all my important stuff, as well as some music and movies.I use a second linux box in my living room to "stream" content via NFS or SAMBA share.The streaming tends to stop several times during playback, and needs to fill up its buffer again before continuing to play.I also have some Windows XP and 7 based computers that connect to this file server.I have noticed that directory listing is VERY slow, and there is a huge lag when I want to save/read a file from/to my home directory.

This is my setup:Ubuntu Server 10.10 64 bit (I have the same problem with 32bit ubuntu)
3 RAID5 arrays with 4 hard drives eachLVM on top of the 3 raid5 arrays.The Logical Volume i use is about 6.5TB, and I use the ReiserFS file systemThis LVM has grown over the years, and has had som replaced disks. So I have used the pvmove, and extend commands a bit.I have tried using IOTop and top to check if there is not enough resources available, but that doens't seem to be the problem.I haven't been able to find out why streaming over the network stops, but I know it is the server that causes the problem.Does ReiserFS have any performance problems with large logical volumes? Would changing to EXT4 or some other FS give any performance gain?

OpenSUSE Hardware :: Slow Performance With Mutexes And MySql On Multi Core CPU - AMD Phenom II X4 965 - With 11.3

Nov 11, 2010

I have installed OpenSuse 11.3 32 Bit in a virtual machine on an older computer on a Windows XP host and on a new computer with AMD Phenom II X4 965 processor.

With sysbench I tested the performance of mutex and on the new computer it is 3 - 4 times slower than on the virtual machine. Other performance tests with sysbench for CPU, memory and threads are faster on new computer like expected. I tested this, because I have a slower performance of table creation in MySql tested with sql-bench, where creation of 10000 tables lasts 45 seconds on the virtual machine but over 400 seconds on the new computer.

I have tested with kernel-desktop and kernel-default but there are not large differences. File creation was tested with bonnie++ and is on newer computer faster as expected.

My questions are:
- Why is the mutex handling on the multi core CPU slower than in the virtual machine and how to speed up this?
- Or is there another reason why table creation of MySql is so much slower on multi core CPU?

OpenSUSE Hardware :: Best NVIDIA Driver For Quadro2 Pro - Slow Performance On Browser Display Video

Jan 27, 2011

I went back to Suse 11.2, it comes with the 'nv' driver for my NVIDIA Quadro2 Pro (64 MB) and I'm getting some slow performance on browser display and sometimes video playing. Not always, I recently saw a 2 hr long movie on Blue Ray resolution, so the problem is not hardware, it's software. I saw several links here on how to install other drivers and a 1-click install link on this page but my question is, since this is an old card... which driver is the best for this card ?

General :: Run Firefox Jailed Without Serious Performance Loss?

Feb 20, 2011

My Firefox configuration is tricky:

Firefox runs at separate restricted user account which cannot connect to main X server.

Firefox uses Xvfb (virtual "headless" X server) as X server.

x11vnc is running on that Xvfb.

On the main X server there is vncviewer running that connect to this x11vnc

On powerful laptop (Acer Extensa 5220) it seems to work more or less well, but on "Acer Aspire One" netbook it is slowish (on a background that firefox is loaded with lots of extensions).How to optimise this scheme? Requirements:

Browser cannot connect to main X server.

Browser should be in chroot jail (no "suid" scripts, readonly for many things)

Browser should have a lot of features (like in AutoPager, NoScript, WoT, AdBlockPlus)

Ubuntu Multimedia :: Firefox Flash Performance Fixed ?

Jan 1, 2011

I posted a few weeks ago about Flash performance in Firefox vs. Google Chrome. Thanks to all those who responded. I finally figured out the problem in Firefox, it was Compiz desktop effects. With effects off, flash in Firefox is just as fast as Google Chrome. I am not sure why Compiz only affects Firefox Flash, but apparently Chrome is not affected. I know there are a lot of posts about this topic, so before driving yourself nuts installing FlashAid, and running terminal commands, try disabling desktop effects first.

Fedora Networking :: Firefox Says "Firefox Can't Find The Server?

Sep 8, 2009

This is really odd - all of a sudden, my firefox says "Firefox can't find the server at www.google.com" , and my pidgin will not connect saying host not found.However, I am typing this on the same computer using Opera. his is absolutely insane. I have no idea what caused it.. command line nslookup works great, and resolves everything.But firefox and pidgin will not resolve anything.

The only odd thing is this in messages:
Sep 8 12:07:41 tklaptop NetworkManager: nm_ip4_config_add_nameserver: assertion `nameserver != s' failed
Sep 8 12:07:41 tklaptop NetworkManager: nm_ip4_config_add_nameserver: assertion `nameserver != s' failed
