Been running 64 bit Vista for a few weeks now, my reliability score’s pretty low (lots of red-balls and app crashes). But things overall seem pretty normal and fast. Running on a Thinkpad T61.
I didn’t prepare for Bitlocker though, only creating a single huge partition. Luckily the Bitlocker Drive Preparatin Tool handles this. As I’m writing it just finished preparation – it took some free space from C: and created an S: partition of 1.5gb which will be the active partition. Hopefully I’ll reboot and things will work.
I’m interested in Bitlocker’s affect on speed and performance. So I’ve created a few informal tests to time things, though I expect the difference to be low – as the product team says, it’s in the single digit percentages.
