Im running Server 2008, SQL 2005 Express and Web Developer 2008 on a virtual pc and as soon as I start doing heavy stuff it gets sluggish. Is there any way to speed things up?

Im on a c2d @ 2.8ghz, 2gb RAM, 320gb RAID, and Ive given the VPC 1.5gb to play with. Ive tried setting the process to realtime on a single core but it was actually slower than std.

DOnt give the Virtual PC more RAM than you allow for the host OS.  That does make a serious difference.
