NT4 memory manangement is different - if there is no server memory pressurer it does not bother reducing the working set as there is no need. 2000 started being more aggresive as people were complaining about excesive page size ( even thou there was little paging)

The time taken seems to increase dramatically from less than a second to almost an hour, depending on how many controls (and their associated objects) are in use at the time. Our app is a fairly straightforward Windows Forms application, but a couple of our forms make use of quite heavily nested controls; it's when these are in use that the excessively long GC times occur. This problem doesn't happen on 2000/XP, and the forms work well. I've tested this by varying the quantities of controls and manually calling GC.Collect() and GC.WaitForPendingFinalizers(). Any idea why we're hitting this problem? Something different about NT4? Cheers, G. -- Graeme Foster ([EMAIL PROTECTED]) Principal Software Engineer Aston Broadcast Systems Ltd.
