Performance difference between windows 7 clean install and upgrade install

[briconroy]

Does anyone know whether there is a difference in performance between doing a clean install of Windows 7 vs upgrading Vista? Any better stability? I'm just wondering whether it's worth the trouble of the clean install.

clean seems to have given me better performance!

Clean is always better since an upgrade can leave "junk" in the Registry and there can be some leftover DLLs that are no longer necessary, but get loaded anyway.
