We have a performance problem with a SCO UNIX V2.1 system. The sar -u
command gives that the system idle percentage is often 0%.
I think we have to many users on the system. What kind of hardware
is recommended for a 30 user administrative system. Sar gives an average
of 200 processes (30 of the 200 processes are Cobol programs, the rest is
sh, getty, etc) and 500 open files.
Is their a tool available to see which process eats the most cpu cycles ?
Thanx in advance.
