Confirmed results from another machine…
Benchmark report for SunSpider, V8, and Kraken on oldmac.local (MacPro4,1).
VMs tested:
"TipOfTree" at /Volumes/Data/pizlo/quinary/OpenSource/WebKitBuild/Release/jsc (r99757)
"LazyOSR" at /Volumes/Data/pizlo/octonary/OpenSource/WebKitBuild/Release/jsc (r99757)
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. Reporting benchmark execution times with 95% confidence intervals in
milliseconds.
