I am having a lot of performance problems since my upgrade my ATI board does not get properly supported (tried a lot but nothing really helps)my keyboard typing is horrable : i have to see at each click of it got accepted ; cannot type text properly screen performance is bad - often the screen greys out and back to color (probably because of driver)

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:
Code:
[12879.434115] irq 22: nobody cared (try booting with the "irqpoll" option)
[12879.434121] Pid: 0, comm: swapper Tainted: P 2.6.35-22-generic #34-Ubuntu

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.

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?
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?
View 5 Replies View RelatedI 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.

View 8 Replies View RelatedI am running the newest linux (ubunbtu 11.04) on an old laptop (2.3 Ghz celeron, 760 mb ram, bios is the latest version). I don't expect it to perform well, it's not a fast processor.But.....it performs so poorly with linux...and I am beginning to wonder whether the machine is broken or malfunctioning. The processor utilization seems high at all times, but I am not sure what is normal/typical.Which of the many benchmark software packages should I use in order to quantify it's performance (or lack there of)? Are there web resources that will list benchmark values of various machines, so I can determine if my punch box is broken or whether it's just slightly slower than other similar machines?

Just installed Sqeeze and works almost flawlessly on my Clevo w870cu. My machine has a realtek wifi card so I installed the vendor specific driver (see below). Wired performance is super, wireless performance however is very bad on Linux. On "Windows 7" (dual-boot, which I never use, only in these cases to sort out problems...) wifi performance is slightly better. My smartphone's visual wifi-analyzer (I couldn't find a Linux equivalent...) showed good signal strength (aournd -50db a 4 m distance from router) an little-to-no interference from neighboring channels.
Here some hardware information:
1) Modem: Motorola SBV 5120 E
2) Router: Sitecom WL-350 (300N)
3) Wifi card: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller
Compared to my laptop notebook with a HD of 5400rpm, the write performance of raid1 on an ubuntu lucid server is unacceptable. In the begining, I installed ubuntu 9.04 server(alternate) using raid1 with two WD 1TB HDs of 7200rpm(Green Power) and then performed dist upgrade to 9.10 and then to 10.04.
I guess the write performance initially was reasonable since the installation and data migration(copy from another computer over LAN) didn't take too much time. However, after upgrading the server to 9.10 or so, I found large file upload through samba or ftp tends to block and time out. It is of no use whether to change the daemon or the client program so that I tried to test the read/write performance on the server to figure out the situation.
To my surprise, using strace I found even a simple program like cp would easily get blocked eventually in a write() system call for decades of seconds. Hence, I perform another disk writing test using dd for data size ranging from 50MB to 1GB. Performance test commands are listed as follows:
Quote: dd if=/dev/zero of=test.img count=[5|10|15|20|100] bs=10M
if the data to write is equal or fewer than 150MB, the command returns immediately at very hight speed but the raid disks starts to sync and busy so that the terminal prompt seems to freeze. I think this behavior is normal under the raid1 configuration, isn't it?
But when the data size is equal to 200MB, the test command blocks for seconds and the write speed is measured at about 16.6MB/s. Of course, the raid disk still starts to sync and busy afterwards. Next, I test writing with data of size 1GB. The command blocks so long for about 770 seconds(<2MB/s) while the same test runs for only 17.49 seconds(60MB/s) on my laptop.
I also burn a Lucid LiveCD to boot the server and mount the raid device to run the test again but the results remain similar. Does that means even I re-install the system on the raid, the problem never disappears?
PS: the disks run under the mode of UDMA6 without change.
I have a dual boot on a netbook with windows and fedora13. When I am on my fedora boot and I try to watch streaming video it comes through in waves or not at all. I do not have the same problems on the alternate boot. There are other performance comparisons where the windows boot runs smoother and faster. Is there any work I can do in order to optimise my fedora boot in this capacity?
