I find this to be an invaluable aid in determining memory requirements:
#!/bin/sh
ps $1 $2 -gaxo pid,user,tt,time,start,state,wchan,rss,vsize,command
################################################################### END
you mention clients, don't forget the size of the shell... tcsh, for
instance takes over 600k resident per, [-O2 -m486 -fomit-frame-pointer],
and around 800k virtual.
BTW: one suggestion. why not include tcsh [possibly ksh as well] as part
of the standard distribution?
