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.
I have been using Windows on my laptop, but recently switch to Fedora 14. However, there seems to be a screen refresh rate issue that i didn't encounter when using Windows. The symptom is that when I scroll down through the browser page, the content become gibberish and unreadable. I have to do a refresh to read that content.
I did some searching on the Internet and found that it may be able to fix by updating driver, but i have no idea what and how to do it. can someone suggest a solution? can i use yum?
I'm wondering if anybody could explain this phenomenon to me. I have just had a box stop on me, probably power supply failure. It was running with an AMD 2GHz cpu, 32 bit, 2GB memory. The Radeon card was using the x-org "radeon" driver and giving upper 3000 to lower 4000 fps according to glxgears.
I have transfered both the radeon card and the hard disc from the dead box and loaded them onto a different one. The new one is running with an intel pentium 4 running at 1.7GHz, 32 bit, 1GB of memory. On this box glxgears reports only upper 600 to lower 700 fps.
OK. It's a slightly less powerful cpu but by only 300 MHz. "top" shows glxgears using 72% of the cpu and the cpu shows that it's loaded at 60%. There is still free real memory and the usage figures for it do not change during the running of glxgears. I am really puzzled as to why there is a fivefold plus drop off in performance.
I mean, the software etc is the same as on the old box - it's using the same disc after all. I can only think that there is something else that is getting in the way but what?
I'm running Natty on an Nvidia 8200 chipset. I found how to change the grub/tty resolution here, but anything I run from tty takes about a full second to redraw the screen. I KNOW this is something simple, but I must be missing it.
When I start yast2 it seems to hang at around 50% (the lower progress bar) while refreshing the repositories. It can sit there for a minute before moving on. Once yast2 has started and I add / remove repos the refresh happens very quickly. It's only when starting that it gets stuck.
This is something that really only started after I upgraded to 11.2. In 11.1 the progress bar would move cross quickly and you could see the various repos flashing up above the progress bar. I didn't bother with it too much but it's starting to annoy me now. It also sometimes just hangs there permanently and I have to abort it.
I've tried unconditionally updating the yast stuff but it hasn't helped. My network connection is fine and I have now problems or speed issues with browsing the repo urls from a browser.
I've got an annoying problem with refresh rates in everything to do with videos. Basically, anything that requires a quicker refresh than using a word processor. This includes flash movies on a website to playing an offline video. In website flash, the video tends to, well flash on occasion. The other sort of thing is pan lines or whatever they're called in videos like a simple .avi movie.
I currently have the nVidia 270.29 drivers installed for my GTS450 card, but this was happening with older versions. My monitor is a Samsung SyncMaster 943 which is detected. The resolution and refresh rates are sort of fixed on auto configuration. What I mean is, is that I can use the drop down menu to change the resolution to a manual option, and then it allows me to select a refresh rate, but only limited to 60 and 75Hz.
This setting will stay as is until I need reboot or restart Ubuntu. Even clicking on Save to X Configuration File is not a keeper. However, here's another problem. Doesn't matter which refresh rate is selected, I still get the above problems. The same resolution and refresh rate yields no problem under Win7 which I've dual-booted with.
The GUI on nautilus is painfully slow to work with. Every time I drag and drop a file I have to wait for the nautilus to slowly shade the whole file window . . . . . . . before it stops and lets me drop the file. I searched for a way to turn off this "animation", but found nothing.
I've tried pcman, but it wouldn't open my files. Thunar insists on copying files instead of just moving them.
I've been using Ubuntu 8.04 for about a year and the wireless has been fine but now it's gone screwy and I can't figure out why. This has happened on my laptop and wife's who uses Ubuntu Hardy also. The speed drops to almost 0 mb/s whenever the signal strength is less than 95%.
It isn't the internet connection as vista (I dual boot) works fine below 95% signal strength. To get the internet speed to be at a level that can load an internet page, I have to within 3 feet of the router!! Both of the laptops don't use ndiswrapper, the internet connected straight away from a fresh install.
I am new to fedora, but not so new to linux. I've got f13 installed on my netbook, and the speed and overall beter-ness? of it made me want to get it going on my desktop. I've installed, and have updated the kernel, and network manager (Along with a few other things). My problem is this; after about an hour or two I get a drop out, unable to reconnect. Until I use 'ifconfig wlan0 down > ifconfig wlan0 up' then it works great for about 10 minutes, slows down, and eventualy drops out. i updated networkmanager in the hopes it may have been that, but it really made only a slight difference.
iwconfig : $ iwconfig wlan0 wlan0 IEEE 802.11bg ESSID: Mode:Managed Frequency:2.462 GHz Access Point: 00:1E:2A:0E:08:50 Bit Rate=54 Mb/s Tx-Power=18 dBm Retry long limit:7 RTS thr: off Fragment thr: off Power Management: on Link Quality=32/70 Signal level=-78 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
I am using a linksys wusb54g > chipset ralink rt2510? (don't quote me on that its from memory). I am also using WPA encription. I am currently messing with those setting to see if that helps.
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.
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.
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.
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?
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
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.
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).
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?
I am having very slow performance from ubuntu 9.10 - gnome - kernel 2.6.31-15-generic when copying files to usb flashdisk drive.It starts very fast(3-4MB/S) but after a while it slows down to speed of 200,300KB/S. 700mg movie file took me around 4hour to copy.
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.
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.
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.
I have this problem. It seems like a new problem to me, but maybe it isn't. When I scroll in web browsers its really slow and erratic but when I'm in nautilus is fine. What could the problem be?
I've just upgraded from a wonderfully working v.9.10 to v.10.04 so I can install Flash and allow video to work. Apparently I can't install Flash into this older version. The performance is now unusably slow and windows move around desktop in a very limited way and cascading menus lag. I did all updates before upgrading as suggested. (The machine is a Toshiba Tecra A4)
I have an old Amilo D laptop (compal cy23 mainboard) which I want to use as a NAS. As I wanted to add a big SATA drive I bought a PCMCIA SATA controller based on Via VT6421 chipset. This is where I have a problem. My drive is very slow (around 8mb/s) with this configuration. Other PATA drive is around 22-23mb/s. My O/S is latest archlinux. Before trying linux
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
I've just installed Slackware 13.37 but there seems to be an issue. i can't change my refresh rates(i want to change ir from 75 to 85 KHZwhich are the only options) as each time i change 85 in KDE from system settings works until i restart X then it goes to the previous setting which is 75.my xorg.conf looks like this code...
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.
