This is great for SunSpider.
Benchmark report for SunSpider, V8, and Kraken.
VMs tested:
"TipOfTree" at /Volumes/Data/pizlo/quinary/OpenSource/WebKitBuild/Release/jsc
"ByValNotInt" at /Volumes/Data/pizlo/tertiary/OpenSource/WebKitBuild/Release/jsc
Collected 60 samples per benchmark/VM, with 20 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.
