What do you mean by very long time?

I am experimenting with a small Condor cluster (Condor 6.6.6, mostly on
Windows-boxes unfortunately) as you can see from my various beginners
mails popping up in the forum.
I have set up a bunch of Windows-machines (Win2k SP6 and WinXP Pro SP1)
and a central Linux-Master-Server.
Submission of jobs works in principle (tested it with the
hello-world-examples from http://www.liv.ac.uk/e-science/condor/hello.html
but sometimes I observe a strange behaviour in that certain jobs need a
very long time until they are beeing executed.
300 second delays can occur if the new job started while condor was
within a 20 seconds frame of the negotiation cycle. you can start the
job by using condor_reschedule.
you can reduce the time by lowering the NEGOTIATOR_INTERVAL value, but
the 20 seconds timeframe is fixed, so for a 60 second interval you have
a 33% chance that your job must wait up to a minute.
If you have to wait for 30 minutes, it would point to a more serious
problem in the negotiation between master and clients.
