hi there
on my new woody-box i experience some major performance problems. thez appeared a day a go and i can not link this to any of my activities...
>>> what i observe:
* there is constantly a hell lot of disk-activity.
* starting X/gdm at boot takes around 2 minutes (restarting goes much faster).
* applications sometimes take ages to start, eventhough right now things run quite well.
* multiple instances of sendmail (currently 3) are continiously running.
* there might be a problem in delivering root-mail although i have set up an alias to myself. /var/mail is empty (no mailboxes there) - the mailqueue is empty right now.
* memory- swap- and disk-usage are in the usual range, hardware seems to be fine.
>>> what i've done so far:
* i did some monitoring using top and ps (see output below) but their output seemed pretty 'standard' to me.
* installed exim instead of sendmail but went back as this did not have any effect.
>>> what i would like to know:
* has anyone any idea how to effectively track those performance-problems?
* how do i monitor disk-activity at all (there is not even a disk-led on my box)?
* any idea why there are no mailbox-files in /var/mail ?
i know these are a lot of questions and i am not even sure if there is any relationsship between them. below is the output of top and ps.
thanks for any advice
