Slowww AIX 4.3
 

I'm running Aix 4.3 on a decently quick 43P-140 332mhz workstation. After
logging in, it takes at least 2-3 minutes for the desktop to appear, and
then a huge lag after launching applications, etc. Its driving me crazy and
its hard to use the computer. Any suggestions? I've tried reinstalling
many times with no luck.


Thanks,
Matt

If you type "vmstat 3 5", what do you see ?

I vaguely recall (it's been some years since I've used AIX) that the kernel has two process queues, and when one is "full" is transfers processes to the other one which guarantees they will be swapped out for some time. There used to be a sample program called schedtune which enabled you to tune the kernel queue to have more than two entries in the first queue(!). Making the value something like 20 made a noticeable difference to the perceived response of the system. Things may have moved on since then, however.
