perf
Benchmark report for SunSpider, Octane, Kraken, and AsmBench on hanayamata.
VMs tested:
"baseline" at /home/yusukesuzuki/dev/WebKit/WebKitBuild/perf-master/Release/bin/jsc
"patched" at /home/yusukesuzuki/dev/WebKit/WebKitBuild/perf/Release/bin/jsc
Collected 30 samples per benchmark/VM, with 30 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.
