Performance is OK: Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on bigmac (MacPro5,1). VMs tested: "TipOfTree" at /Volumes/Data/primary/OpenSource/WebKitBuild/Release/jsc (r191393) "GenericWorklists" at /Volumes/Data/primary/OpenSource/WebKitBuild/Release/jsc (r191393) Collected 7 samples per benchmark/VM, with 7 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.
