1%/4% Linux Tp4 regression 2010-09-15 The regression is 4% on 64-bit Fedora 12 http://mzl.la/dcAah8 http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=7cf62a2a821e&tochange=69dd0ebbd3bc On 32-bit Fedora 12, there was only a 1% increase from ~372 to ~384: http://graphs.mozilla.org/graph.html#tests=[[38,1,411],[38,1,412],[38,1,413],[38,1,414],[38,1,415],[38,1,416],[38,1,417],[38,1,418],[38,1,419],[38,1,420],[38,1,421],[38,1,422],[38,1,423],[38,1,424],[38,1,425],[38,1,426],[38,1,427],[38,1,428],[38,1,429],[38,1,430],[38,1,554],[38,1,555],[38,1,556],[38,1,557],[38,1,558],[38,1,559],[38,1,560],[38,1,561],[38,1,562],[38,1,563],[38,1,564],[38,1,565],[38,1,566],[38,1,567],[38,1,568],[38,1,569],[38,1,570],[38,1,571],[38,1,572],[38,1,573],[38,1,678],[38,1,679],[38,1,680],[38,1,681],[38,1,682],[38,1,683],[38,1,684],[38,1,685],[38,1,686],[38,1,687],[38,1,892],[38,1,893],[38,1,894]]&sel=1284537614,1284679586 with an intersecting range: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=77e11b95175f&tochange=10257eea7533 MacOSX 10.6.2 results show a big Tp4 improvement which is clearly in the range http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=7cf62a2a821e&tochange=ec6c7ae80489 so it seems likely that bug 594882 or bug 556734 is also involved here. WINNT 6.1 results may also show an improvement, though it is harder to see from the graphs.

By 'improvement' you mean that the timing is better or worse? I believe this is caused by bug 594882, it postpones resume of http channels for a bit and also there has been reintroduced asynchronous cache item obtaining. Both may slow down, however, the former seems more probable. I don't immediately think we can do much about it.

(In reply to comment #1) > By 'improvement' you mean that the timing is better or worse? "improvement" means better. Things got better on Mac and worse on Linux (as measured by Tp4).
