[plt-scheme] Appalling performance of DrScheme on Windows

Thanks to all who have provided information so far!

One extra question to those who see bad behavior when DrScheme has been
idle for a long time: do you use Help Desk's search feature?

I ask because a Help Desk search goes through a servlet (using a local
instance of the web server that runs through pipes instead of TCP
connections). I wonder whether servlet session time-out could have
something to do with the problem (either in the web server or in
MzScheme's support for the web server).

Thanks,
Matthew
