In a set of comprehensive Windows Web browser performance tests conducted by Betanews on August 7 -- our first test of browsers running on the final Windows 7 RTM Build 7600 distributed by Microsoft yesterday -- the five major families of browsers tended to run 13% faster on Windows XP Service Pack 3 than on Windows 7, and 29% faster than on Windows Vista Service Pack 2.

That reflects a decline in the speed gap between XP and Win7 of about 1%, from tests conducted comparing XP-based browsers to those running on Windows 7 Release Candidate Build 7100. Some browsers are faster in Windows 7 RTM, although Mozilla Firefox 3.5.2 ran just a tick slower.
