Slackaware 12.2 is giving high response time for applications

troj3n · 02-09-2010, 06:00 AM

Hi Guys

I am using Slackware 12.2 on my laptop
compaq presario V2356AP
Intel centrino 1.6ghz
1 GB Ram
and Slackware is installed on 16gb partition with 10 gb free now

When i installed it was fine over a few days slackware is giving me high response time.

while playing videos it is getting stuck
firefox is giving bad responses and even konqueror

please guide me

I heard that slackware is one of the fastest linux
and is old hardware friendly right

what might be the problem

You may be CPU bound when running these tasks. What does your CPU usage look like while watching a video? Watch the output of 'top' as you use the laptop. What type of videos are these? Flash videos like on YouTube or avi videos viewed with mplayer or similar?

see the problem is not only with video .
i will explain

when i boot into my slackware 12.2 the performance is fine for quite some time
then after that all the application is taking more time to respond. be it vlc or firefox or konqueror

has it got something to do with hack,
i dont have a firewall

i am not able to setup one because i use azureus and the one guard dog i tried blocks azureus no matter what i do

and yes the cpu usage is on top at this time when stuff gets stuck

please help me. its quite suspicious

Did you run the 'top' command in the terminal, as crabboy suggested? It will tell you which processes are eating your CPU.

Again the same thing has happened and now i ran top as root

X is the culprit taking 56 % cpu
and disk cache taking 60% of memory and 37% by application data

I have 1 gb memory and 1 gb swap as told earlier

What can be done. when this happened i was watching a film avi format in mplayer. the movie got stuck then i quit it. now firefox is operating damn slow.

Please help me

in kde 3.5 i have configured the desktop settings to the lowest for fast performace. but this is wht i get

what can be done

Please help

One thought

has it anything to do with a bad hard drive

also another thing is that my linux is shutting down frequently saying critical cpu temperature has reached.

when in windows it simply turns off. but in windows things are not slow.

Try renicing the Xserver process. It'll stop it hogging your cpu and let other tasks get a look in. I've found this can help with responsiveness when X is under heavy load.

You'll need to find the right process id and you'll have to run the command as root.

Code:

gazl@nix:~$ ps -e | grep X
 2558 tty7     00:00:43 X
root@nix:~# renice +1 2558
2558: old priority 0, new priority 1

If it works for you then you can alter your Xserver to always run with this reduced priority.
