Created attachment 173079 [details] Benchmark This page takes 7 seconds in Safari, but 19 seconds in Chrome. In doing a trace it seems we spend all our time in V8 bindings, seemingly in GC. A trace of Safari shows they spend a lot of time in WebCore::JSNodeOwner::isReachableFromOpaqueRoots as well. Webkit.app nightly: 7571 ms Chrome Canary Chrome/25.0.1320.0 (WebKit 133816): 18620 ms This case is probably pathological because Firefox 17 takes 35 seconds and Opera never finishes loading. I don't have IE10 on hand to test there. The origin of this benchmark is Bug 73853.
