Some performance. Note that since I ran all of the benchmarks, I discovered this thing: https://bugs.webkit.org/show_bug.cgi?id=126802 VMs tested: "TipOfTree" at /Volumes/Data/pizlo/cStack/OpenSource/WebKitBuild/Release/jsc (r161705) "FixCheckExec" at /Volumes/Data/fromMiniMe/cStack/OpenSource/WebKitBuild/Release/jsc (r161705) "FTL" at /Volumes/Data/pizlo/cStack/OpenSource/WebKitBuild/Release/jsc (r161705) export JSC_useExperimentalFTL=true "FTLFixCheckExec" at /Volumes/Data/fromMiniMe/cStack/OpenSource/WebKitBuild/Release/jsc (r161705) export JSC_useExperimentalFTL=true Collected 10 samples per benchmark/VM, with 10 VM invocations per benchmark.
