Hi, all

I found that on my arch (64bit), GUI program which use TK lib runs versy slow, and it also suspend the KDE for a long time to response to the keyboard.

I found that when those program begin, the hard disk LED blink many many times.

The example of that program is amsn and gitk.

Any one have the same phenomena? or anyone have some idea about it?

TK package version is 8.5.11-1, seems the most recently version.

Thanks for any response!

Gitk works fine for me, although my own repo can be a bit small for a comparison test. So can you figure out if the problems are I/O bound or CPU? Are you loading a big ~2Gb repo with gitk or just a small one? Just a small one --- several kb source code. I think it has nothing todo with the GIT, it is something about TK lib. aMSN and other GUI program using TK runs very slow, and seems they are torture my harddisk. When starting, the keyboard nearly lost response to other programs....

Thanks for your kindness reply! I'm almost sure that it is not the swap partition's problem. My KDE runs prefectly, but when any GUI program which use TK library starts, the hard disk will keep busy for VERY long time, and the keyboard can not input into other program for a long time. When the TK related GUI program initialization finished, It runs ok, except the same thing occurs when it pop up any diaglogs (for example, aMSN automatically pop up a notice box when a new friend appear online). I have not log info currently. And it needs some time to get more info about it... On 2012-05-30 00:00:31, Martti K黨ne wrote:

you should be able to catch stuff like this with strace and kernel.log. btw, do you have a swap partition on said "tortured" drive?

let's see if I can test in the next couple of days...

cheers! mar77i

Hi, all the Kindly friends Here is another new discover: I run aMSN remotely. That is to say, I use xhost cmd to allow some remote machine can use my laptop as the X11 server, and one the remote machine, setup DISPLAY environment variable correctly. When run, The X11 server machine's hard disk begin to blink endless and the keyboard lost respones. I had use strace to hacking the problem. and found that when it happen, the program is in poll. The fd param of poll is a socket. Locally and remotely run the TK related program, the FD is created differently: local running is socket(PF_FILE, SOCK_STREAM|SOCK_CLOEXEC, 0) = 5 remote running is socket(PF_INET, SOCK_STREAM|SOCK_CLOEXEC, IPPROTO_TCP) = 5 And that is right I think. X11 protocal should run on the most fast way it found. Now, I can say that: This problem is something related to the TK and X11 library. It has nothing to do with the GUI program's function ---- no git repo problems(when run gitk ), nor networks problems( when run amsn ). More testing should be done, But I can't spend too many time on this. By far, the company can not allow me to hacking the linux system all day and all night...... Does anyone has any other GUI program that using TK library? We can try more softwares..... On 2012-05-29 19:51:42, Patrick Burroughs wrote:

This might be a long shot, but could you have an environment variable or something set that's triggering a debug state? Maybe lots of logfile writing?
