IPLOT - very slow

Our office recently added iplot while our main office has had it for a while now without any trouble.  Everyone in our office is having all kinds of problems with iplot being VERY slow to load the ips files and then if you need to change any of the settings it seems to take forever for the dialog box to come up and then it takes a while to apply the settings to the files.  There is something that is making our configuration slower than the main office.  Has anyone had any similar problems?

I just today timed the time it takes to plot through Iplot and it took 7 minutes to update, assign a set file and print 4 files while through print organizer using the same iplot scripts took just 30 seconds.  I posted this yesterday in another forum but I don't think many people go into that one so I re-posted.  I know, I'm bad.

Thank you,
