Benchmark report for SunSpider, V8Spider, Octane, Kraken, JSBench, JSRegress, and DSP on oldmac (MacPro4,1). VMs tested: "TipOfTree" at /Volumes/Data/pizlo/OpenSource/WebKitBuild/Release/DumpRenderTree (r154377) "InlineAlloc" at /Volumes/Data/fromMiniMe/primary/OpenSource/WebKitBuild/Release/DumpRenderTree (r154377) Collected 12 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.
