Make sure the amount of memory you are using leaves enough for your mac. Also, what kind of mac are you running it on? I tried P10 on an older MBA that only has 4gbs of ram and an UVC processor and I still get really good performance out of Windows 7. This may be a Windows issue as well.
What kind of Mac do you have? Does it use a spinning drive or an SSD?
A couple of other things. Quicken is horribly written. I run it natively sometimes and it's slow. Silly things like resizing a window and it feels like it's locking up. Not related to Parallels though.
As for where I see improvements on, it's mostly things like launching programs, boot times, and since I'm a developer compile times on large programs is a huge improvement. I also noticed moving windows around, like the UI is really smooth and fast, but NOT always and I'm not sure when it decides to be a little choppy and when it's fast. Maybe someone at Parallels has an idea?
