No, I meant Red Hat's kernel 2.4.20-54. It's based on 2.4.21-pre4 with patches from Alan Cox, Arjan van den Ven and several other people from RedHat. > Your vmstat traces were showing tons of user time as well as system > time.

I have attached to this message "top -d1 -b" and "vmstat 1" command outputs, compressed with bzip2 to shorten the message length. I hope they will help in clarifying things a little. Both command were started up a while before clicking "Reply" and a few seconds after the message window opened up, just to let the system stabilize. > Well certainly the IO stream _looks_ like it is stuck in IO-wait a lot. > > It is strange that this has been happening for a couple of months and seems > to only affect Felipe Solana's copy of evolution.

A little bit more about my scenario: I'm running Red Hat Phoebe Beta 3 (what will in fact turn 8.1) with glibc-2.3.1, Evolution 1.2.2, XFree86 4.3.0 and KDE 3.1. I think Evolution has been compiled against glibc-2.3.1 and so it will be using NPTL. As for XFree86 and KDE, I compiled them myself and I'm sure they are using glibc-2.3.1 and NPTL. Please, dont' hesitate in contacting me for further investigations. Thanks!
