I have seen similar performance problems related to the timestamps 
found on several important files used by ps(1).  If any of the critical 
files have a bad timestamp, ps will rebuild the file /etc/ps_data every 
time you run it, causing the system to seem verrrrry slooooow indeed.  
If the timestamp on any of the following files or directories is incorrect, 
it can cause the type of behavior you have observed.

     /dev
     /dev/console
     /dev/kmem
     /dev/mem
     /dev/syscon
     /dev/systty
     /etc
     /etc/passwd
     /unix
