Performance

Hi *,
I have IS 6.1 standalone without Broker. I have about 4000 processes on the machine. My CPU is about 80-90% idle, so OK.
But when I look at the process-steps the time between the end of step A and the beginning of step B is very long (2 hours)

Who do I have to tun the machine ?

Hope anybody can give me help.
Ralf
