I had a similar question Reason Visual Studio would be slower on 64-bit dual core machine?
Now i want to know if programming is much slower on windows 7 (64bits) then vista or XP (32bits)? (i never tried vista) should i dev on XP as much as possible? i found it strange when running a webpage (visual studio 9) it would take a page 3sec to load while it being instantaneously on the same laptop in XP.
Should i expect poor performance in non web applications as well?
-edit-
Answer is here. Whcih explains why only loading webpages was slow https://stackoverflow.com/questions/1055528/is-development-programming-on-windows-7-slow
