Hello
It's an issue bugging me from quite a long time, so finally I decided to share my anxiety :-D
Is it normal that both desktop environment actions (clicks, moving windows around, even moving the cursor) and keyboard input slows down when disk is under heavy load? It happens for example when I try to unpack something from a big archive or load a big file in a program. Whole computer runs then like Crysis on 512MB RAM, for me it's unusable. I think my config is the key here, so here it is:
Linux asus.k50in 2.6.34-zen2-ARCH-20100812-stable-06977-ge2287d6 #8 ZEN SMP PREEMPT Thu Aug 12 20:54:24 CEST 2010 x86_64 Intel(R) Core(TM)2 Duo CPU T6600 @ 2.20GHz GenuineIntel GNU/Linux
GeForce 102M 512MB
XFS filesystem on every partition.
KDE4.5.1 + all available updates.
Thanks in advance for any hints.

* Amount of RAM?
* Do you have a swapfile or -partition?
* What do you see in the output of 'top' when this happens?
* Do your logs tell you/us something?
I have never seen this behaviour. It is normal, f.e. on an older machine that when doing a pacman -Sy, the system is less responsive or that (even on a newer system) when copying large amounts of data from one HD to another that file operations are slowed down. It is not normal that your desktop is affected by this.

x86_64
See thread.

@zenlord
4GB RAM
2GB swap
Nothing unusual in top. Around 40% cpu use by unrar, but X is also eating up around 20-30% all the time.
What statements should I look for in logs and, first and foremost, which logs should I seek though?
And yes, bauerbill -Syu is also causing that annoying behaviour.

iotop and ionice may help.
Have you tried rebase and other tricks for bauerbill?

@karol
I didn't know about these two. Thanks.

That might be my issue, compiling the latest zen-stable git kernel right now. I know that's not 2.6.36rc, but still worth a try I assume.
Bauerbill manpage really helps with "search for more info in Rebase module"... Where is that?

Apparently there is a patch for 2.6.35 kernel for this issue. I haven't tried it though.

Don't do that. Someone may have a similar problem, so please post where is it :-)

Excellent, compiled kernel with NO_HZ=n and that's what I call the desktop now.
