perf results: Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, and JSRegress on Saams-Mac-Pro (MacPro6,1). VMs tested: "og" at /Volumes/Data/WK/os-a/OpenSource/WebKitBuild/Release/jsc (r190248) "phantomLocal" at /Volumes/Data/WK/os-b/OpenSource/WebKitBuild/Release/jsc (r190248) Collected 4 samples per benchmark/VM, with 4 VM invocations per benchmark. Emitted a call to gc() between sample measurements. 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. og phantomLocal SunSpider: 3d-cube 6.7830+-0.3832 6.4853+-0.7601 might be 1.0459x faster 3d-morph 6.3361+-0.1708 ? 6.5338+-0.3053 ?
