Slackware :: Performance Loss Since Upgrade To 13.1?

Jun 16, 2010

Since I upgraded to Slackware64 13.1 my system feels slower than before (Slackware64 13.0).I paid attention to the documentation (changes_and_hints.txt, readmes etc.) regarding the update. The only thing I changed is, that I used the KDE-4.4.4 packages of AlienBob instead of the KDE-4.4.3 packages of Slackware.

But since AlienBob at his blog wrote, "Although it seems (by looking at the changelog between 4.4.3 and 4.4.4) that there were no spectacular updates in the latest stable KDE Software Compilation, I got some feedback that 4.4.4 does feel �snappier� than the 4.4.3 which is part of Slackware 13.1.", I thought it would be a good idea to use these packages.

I also recognized a few crashes in KDE, which I didn't have before so often. Therefore I moved the .kde to .kde_bak and configured kde new. This improved the behaviour regarding the crashes, but it still seems not that stable to me like the KDE 4.2 in Slackware64 13.0.Did anyone recognize similar problems after the upgrade, or can give some hints how to solve it?

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 Networking :: Very Poor Wireless Performance - Packet Loss

Aug 5, 2011

I have ubuntu lucid running on Dell 230 PC, linksys WPN600 N wireless PCI network card connecting to a Cisco E3000 dual channel router.

Kernel: 2.6.32-33-generic
Installed Ralink driver v2.4.0.0

iwconfig shows that the bit rate is 130Mb/s and link quality is 98/100. I'm using the wcid network manager instead of defaul gnome one. I'm getting lots of packet loss and performance is very bad. The connection is practically unusable. I've tried installing the compat wireless backport package but that did not work at all.

Ubuntu :: Power Loss During Upgrade To New Version

Apr 2, 2010

Today, I was upgrading my desktop from Jaunty to Karmic (a little behind schedule, I know). All packages downloaded successfully, and then the computer began the process of applying all of the updates. During this period, at some point, it lost power. Now, of course, it won't boot.

Fortunately, I have a separate /home/ partition, and it was unmounted during the upgrade process. So, my personal data and settings are fine. But the OS is useless.

I'm guessing that I'm completely buggered here, and there is nothing that I can do except re-format the Ubuntu partition and clean install Karmic from an install disk.

Slackware :: Data Loss After Sudden Reboot On Xfs

Oct 25, 2010

I have a laptop running slackware-current. The disk is /dev/sda and the root 'sda1' is xfs formatted (there is also linux swap at sda2).

recently I was trying to setup openvpn and had to copy a folder with configuration files from /usr/doc/openvpn_<version>/easy-rsa to /etc/openvpn.

I am sure the copying completed cause I got a prompt, but a few seconds later the battery died on me. When I got mains and powered it up, I could see the directory I copied under /etc/openvpn, and the files where all there too. but they all contained nothing. i.e. they had a size of 0.

I read [URL] Fthat an external journal filesystem for root is not supported. I am not sure If it applies to my situation though. As in does it use an internal journal instead?

and the bottom line is: shouldn't the copying have completed successfully? shouldn't I be worried, that this copy failed?

Ubuntu Installation :: Loss Of Internet Connection After Upgrade From 8.04 To 8.10?

Feb 27, 2010

Loss of internet connection after upgrade from 8.04 to 8.10 Like the title says, I lost my internet connection after upgrading my Ubuntu system from 8.04 to 8.10.I used the downloaded automated method. It appeared to work fine on its initial reboot into 8.10. But I noticed the internet icon indicated loss of connection. Even so, I was still able to browse the net through Firefox. But then when I rebooted the next day the opposite was true: the connection icon indicated connection, but Firefox would not actually connect, nor would update manager. It has been like this since. This is a dual boot machine, and the Windows XP Pro side still connects to the internet as usual, no problems.So how can I make my new 8.10 system connect to the internet?

I use a Motorola SB4200 cable modem

Slackware :: 40-75% Packet Loss On Average With Wireless Networking 13.0?

Jun 26, 2010

I am running Slackware 13.0 on a old dell dimension 4500. The install went fine. sound worked, graphics where good. Everything was going perfect. until i worked on wireless.i have a realtek rtl8185 wireless chipset card. I got the wireless. Linux wireless driver. It worked on both Mint 5.0 and backtrack I untar the file. cd to the dir and type make then make install and reboot. like I have always done.

I was having to fight with wpa_gui and finally got it working but then it would go in and out on the connect and disconnect feature. so I tried using iwconfig. did not get muc luck with that either so i installed wicd and finally got a ip address after fighting with it would give me in a ping like 75% packet loss. so I read a lot of post and try to find stuff before I post. and while reading I learned that you guys normally ask for info on the hardware and software so here you go. but I will say first that I read about adjusting the mtu to fix packet loss, I showed some of the changes I made in it around the pings I know it is a mess I am sorry I tried to make it readable. if you need more information let me know. I cant get online using a web browser or if I can only for one or two pages. any help would be great. thank you.

Ubuntu Installation :: Upgrade To 10.04 Leads To Loss Of Correct Screen Resolution / Wireless Networking / Sound

May 4, 2010

Excited at seeing the new features in 10.04, I clicked the Upgrade button tonight. I am now really regretting it! Problems:

1. My screen resolution should be 1280x1024 but the System>Preferences>Monitors control panel only shows 1024x768.

I think I have onboard Realtek graphics. Do I need to install proprietary drivers? Everything worked fine out of the box with 9.10!

2. The sound isn't working. Again I think I have onboard Realtek sound, and again it used to work fine without any intervention from me...

3. Although on first startup wireless networking was working fine, I restarted to see if that would solve the display issue, and wireless networking stopped working too!

I have an RaLink wireless card.

When I used Grub to choose, I got some error messages at startup (e.g. mount couldn't mount /dev), but then it did eventually start up and the sound and wireless networking are working again. But the resolution is still not fixed. It is now offering 1152x864, which it didn't previously, but no 1280x1024 (my screen's native resolution).

Slackware :: Performance On Different Brands Of Cpu?

Jul 17, 2010

Does slackware run slower on amd cpus compared to intel? I just read some articles on compilers optimized for intel cpus via the 'GenuineIntel' check. CPUs' not bearing intel cpuid will be run in non-optimized mode. It's part of Intel & AMD anti-trust settlement.

Just asking if someone could elaborate on the matter.

General :: Disk Performance Slower After Upgrade To 4GB RAM

Oct 19, 2010

I am running openSuse 11.2 (32-bit), my CPU only supports 32-bits. I have a hardware RAID device. My system has 4GB of RAM. When I configure my system to only use 3GB, 2GB, or even 1GB, using mem=1024M in grub, my RAID performance is much better then when letting my system use the default 4GB available.Can anyone explain to me why this is? Is there anything I can do, i.e. kernel configuration, that will help performance when running with all 4GB enabled?

Ubuntu Networking :: WIFI Performance Degraded After Upgrade To 10.10

Jan 12, 2011

I would like to re-raise this topic that I have seen on other discussion boards but seems to be going no where.I have been using Ubuntu for many years now having switched from other distributions. All my machines ran some version of Ubuntu, until just recently. I upgraded my personal HP TX2500 from 9.04 to 10.04. No problems. After 10.10 had been out for a while I upgraded again. The wireless would drop when busy/(signal slightly weakened) etc. It would not function again unless the wifi module was reloaded.

Then I installed 10.10 on my HP NC6400 the same thing occured. I installed Ubuntu 10.04 instead. It seemed no better. After some Googling, it seemed I was not alone. I tried all the suggestions I could find and none of them worked. One suggestion was to install Fedora 14. This works perfectly on the nc6400. The HP TX2500 has been reinstalled back with 10.04 where the wireless seems ok and I assume I am stuck there for a while.

Now my question is why would the networking behave this way for Ubuntu 10.10 (10.04 as well on the NC6400) but wireless on Fedora 14 is perfect (I mean really good! Better than either Ubuntu 10.04 or 10.10 on any of my laptops) on the NC6400. I am hoping that we can find a way to fix this, otherwise I will likely have to drop Ubuntu completely because I do not have an upgrade path for laptops. There must be many other users in the same position who are not discussing it and just rebooting each time this occurs. This must give a negative perception of otherwise great software.

Ubuntu Installation :: Disk IO Performance Degrades Horribly After Upgrade To 10.10?

Oct 18, 2010

I upgraded my old Kubuntu installation to 10.10 Maverick Meercat and I am now experiencing a really annoying problem. I boot my computer and everything seems fine for a while, but eventually my disk performance drops to horrible levels. It's not gradual. It's fine one second and then abysmal the next.

If I do "cp file1 file2" and then kill the cp process after 10s, there are only a couple of MB copied.When I run dmesg after the performance degradation, I see this:

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.

Slackware :: Severe Performance Degradation In 13.37 - Taking 2 To 3 Times Longer

Jun 17, 2011

we bought a dual 12-core Opteron machine (Supermicro H8DGi board). Installed Slackware 13.37 and performed some few tests. We observed that performance quickly degraded as the box became loaded. For instance, a lonely task may took "t", but when running 24 of them at the same time (fully loaded box), it may took 2 to 3 times longer. From some test we did (tinkering with BIOS, moving memory modules, etc) we came to the conclusion the problem was due to a terrible memory managment. Finally we solved the problem by recompiling the kernel and taking the .config file from OpenSuse. Thus, there must be something to be tweaked in the standard Slackware .config file

Slackware :: Flash Performance Salix / Move The Mouse, Then The Whole Picture Freezes?

Apr 2, 2010

I installed SalixOS on my laptop just to play with when I'm bored. My laptop is nothing special, it's a couple of years old has a pentium dual core t2390 at 1.86Ghz and 3 GB ddr2 RAM with Intel video.

I then have a beast i7 920 clocked to 3331Mhz 6GB RAM, and an NVIDIA GT220. Full screen ..... at 720p is fine unless I move the mouse, then the whole picture freezes. Persistant mouse movement will freeze the screen for a few minutes. This machine runs both slack64 current and slack13 32 bits.

The slack box does much better with 32 bit flash than 64, but it still doesn't do nearly as well as the laptop.

With Salix and Slack being so close to each other supposedly I can't figure out why the hardware seems to be irrelevant. The only thing I can think of would be the video codecs installed by Salix, whereas I built a bunch of codecs myself for Slack.

Ubuntu :: Ondemand Vs Performance - Increases The Clock Speed To Performance When The CPU Is Under Load

Jul 31, 2010

I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

Slackware :: Image / Icon Trouble After Slackware-current Upgrade

Jan 22, 2010

I recently upgraded to slackware-current from Slackware 13 via slackroll, and have only encountered one problem. My file manager no longer thumbnails images, and icons (mostly PNG) aren't appearing no matter what GTK theme is set. Running from the command line produces no errors, and when brought up in something else (say feh /path/to/icon.png) it works perfectly. This is the only hitch I have encountered so far. The same thing happens with emoticons in Pidgin. Does anyone know of a fix?

Slackware :: Upgrade To 13.1 From 12.2?

Jan 14, 2011

I tried to upgrade from 12.2 to 13.1 using slackpkg but, by some reason, it did not upgrade and bash gave me error at any command I tried to use. I tried to use the boot CD but still, I couldn't use chroot. Desperately, I mounted the hdd partition into a directory and I installed all the packages from slackware/a directory (with --root /mnt/disk option). Surprisingly, I rebooted and the system successfully loaded the new kernel. Since I installed only the "slackware/a" packages, I would to know which would be the next step to fully upgrade the system. I intend to upgradepkg all the directories from dvd "slackware". Is this a good solution? If yes, which should be the next packages that should be upgraded: "slackware/l", "slackware/ap", "slackware/d" ?? I'm interested in the order of the directories that should be installed.
