I'm currently trying to figure out why a friend's 1GHz PIII based system is doing a spot on impersonation of a 500MHz K6-2 or so. This thing plods along like you wouldn't believe. He's not getting anywhere near the performance he should be.

The system seems to be doing an excessive amount of caching even though there is 384MB of RAM installed (on XP Home). I have done thorough scans for viruses and spyware and the system is clean.

I immediately thought memory leak. A look at the task manager shows that his e-mail client (Incredimail) is always running in background and seems to be using an exorbitant amount of memory, so right now that's my prime suspect.

Anyone here dealt with this app before? Is this thing a known troublemaker or am I barking up the wrong tree?

That seems to be an awfully high price to pay to have goofy cartoon characters notify you of new e-mail...
