Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on Basiles-MacBook-Pro (MacBookPro11,3). VMs tested: "Conf#1" at /Volumes/Data/Baseline/OpenSource/WebKitBuild/Release/jsc (r182938) "Conf#2" at /Volumes/Data/Temp/OpenSource/WebKitBuild/Release/jsc (r182938) Collected 6 samples per benchmark/VM, with 6 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.
