We'll need a good bit more detail to help find a root cause here. In
general, STAF is designed for minimal overhead (when idle). So, if you've
got a Perl script that you run from the command line on a system and it
takes X amount of time to run (assuming STAF isn't even installed), then
it should still take basically X amount of time to run if you have STAF
execute the command for you. Any differences would almost certainly be
due to environment differences (different user, different environment
variables, etc.)
Let's get some basic information and progress from there.
What operating system are you using?
What version of STAF are you using?
What type of test are you running (just a high level overview)?
How are you invoking it without STAF?
How are you invoking it with STAF?
It would also be useful to look at "top" (on Linux) or Task Manager (on
Windows) to see if STAFProc is actually consuming significant CPU cycles
or using large amounts of resident heap. If you see that it is, please
post some stats/numbers for us.
Finally, if it is consuming a lot of CPU, you will probably want to turn
on tracing (see sections 4.11 and 8.18 in the STAF User's Guide) so that
you can see what activity is occurring within STAF. It would probably be
best to trace to a file so that you can post the trace as well.
