Hello!

We've built a fairly big intranet system for a local company. They're now reporting that the system slows down more and more if they leave the system running (i.e. the web page visible). This happens on both PC's and one Mac. So now I'm of course wondering whether there's a list of known things that can slow a system down? We've developed using mainly jsolait Javascript. The only exclusion to that is that we're using Rico grids to display some lists. The server side is written in PHP using Ajax. We mainly use urllib.sendRequest() calls to update things and request new content. The thing that worries me is that we've got one central object that's constantly checking for updates (750ms intervals, with setTimeout). Is that likely to be the culprit, or do you have any other ideas?
