  • I’m no longer able to reproduce the Windows cold startup regression from 3.5 to 3.6 reported in bug 517741. I turned of SuperFetch, which resulted in more stable numbers, but there was no visible regression, even in builds going back a couple of months. Juan tested on Windows XP and found the same. The current numbers show a 27-30% *improvement* in cold startup time on trunk, and up to 8% on 3.6.
