We have a Balance 8 with 16mB RAM and 8 CPU's, our load average is
normally around 0.5. A ps doesn't take more than 1 sec.
Here's the ouput of a 'time ps -x':

  PID TT STAT  TIME COMMAND
 5500 ic Z     0:00 <defunct>
  220 ic I     0:09 -msh (msh)
  838 ic I     0:25 sysline -pjbDhim
  839 ic S     0:14 -msh (msh)
 4516 ic I     0:02 rn
 4536 ic I     0:00 /bin/sh -c Pnews -h /user/staff/hanst/.rnhead
 4537 ic I     0:02 Pnews /usr/local/bin/Pnews -h /user/staff/hanst/.rnhead
 4570 ic S     0:04 /usr/ucb/vi /user/staff/hanst/.article
 5501 ic S     0:00 sh -c time ps -x
 5502 ic S     0:00 awk {
 5503 ic R     0:00 pstat -T
 5504 ic S     0:00 time ps -x
 5505 ic R     0:00 ps -x
        0.8 real         0.1 user         0.5 sys  

I don't know what is wrong with your ps, but it isn't normal.
