Latest numbers, after merging.
TipOfTree: r94996
TipOfTreeDyn: r94996 with tiered compilation enabled
OSREntry: r94996 with this patch and tiered compilation enabled
Benchmark report for SunSpider, V8, and Kraken.
VMs tested:
"TipOfTree" at /Volumes/Data/pizlo/OpenSource/WebKitBuild/Release/jsc
"TipOfTreeDyn" at /Volumes/Data/pizlo/quinary/OpenSource/WebKitBuild/Release/jsc
"OSREntry" at /Volumes/Data/pizlo/octonary/OpenSource/WebKitBuild/Release/jsc
Collected 12 samples per benchmark/VM, with 4 VM invocations per benchmark. Used 1 benchmark iteration per VM invocation for warm-up.
Used the jsc-specific preciseTime() function to get microsecond-level timing. Reporting benchmark execution times with 95% confidence
intervals in milliseconds.
