[plt-scheme] Appalling performance of DrScheme on Windows

I haven't noticed this problem.

DrScheme on the 2 windows machines I use  takes ages to start up.  It also takes ~1 second to evalute the first expression typed in the prompt.
After that though it's reasonably OK, even if left for a long period.

But, I've noticed DrScheme hammers memory quite hard, when minimized in Windows it uses ~5MB.  If you then maximize it and hit "run"  this goes up to ~56MB.
Could it be the problem people are experiencing is something to do with using a virus checker than checks pages as they are loaded into physical memory?
AFAIK no virus checker works this way though.

Why does it use so much memory anyway?
