Solaris 10:

If you want to count  number of processes in the Interactive class
casued by interactively logged on users.

  ps -elc | grep IA | wc -l

Default number of user procs  is 29.995
youll need a 100 MB Ram  per user
each JDS user will run an average  of 35 processes

29995/35  = 857 users  *100 MB =  86 GB  Ram

therefore the smallest  machine where this can become a concern
is a  SunFire 2900  with 12 ultrasparc IV CPU  and 96 GB ram.

This is wrong, as most of the memory allocated would be pointing to the same
phsyical mapped pages hense shared.
