Benchmark report for JSRegress on oldmac (MacPro4,1). VMs tested: "r166074" at /Volumes/Data/pizlo/secondary/OpenSource/r166074/WebKitBuild/Release/jsc "ToT" at /Volumes/Data/pizlo/secondary/OpenSource/WebKitBuild/Release/jsc (r166244) "Getters" at /Volumes/Data/fromMiniMe/primary/OpenSource/WebKitBuild/Release/jsc (r166244) Collected 4 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. r166074 ToT Getters Getters v. r166074 chain-custom-getter 158.2083+-0.1793 ? 160.7440+-19.8519 155.0351+-0.6956 ^ definitely 1.0205x faster chain-getter-access 279.1823+-8.1286 ? 280.4161+-8.0387 ^ 33.7815+-0.4777 ^ definitely 8.2644x faster getter 163.8446+-2.9393 ? 168.8126+-5.2703 ^ 18.7115+-0.4216 ^ definitely 8.7564x faster proto-custom-getter 164.6567+-19.4528 161.4323+-0.1810 ? 167.7127+-19.7281 ? might be 1.0186x slower proto-getter-access 278.1840+-10.8798 275.6373+-8.6379 ^ 33.7239+-0.3456 ^ definitely 8.2489x faster simple-custom-getter 524.4769+-0.5701 ! 535.9200+-0.2769 ? 566.0511+-73.2732 ? might be 1.0793x slower simple-getter-access 461.0245+-2.0153 446.8181+-21.3558 ^ 52.0341+-0.4183 ^ definitely 8.8600x faster <arithmetic> 289.9396+-1.8063 ? 289.9686+-4.5887 ^ 146.7214+-9.6163 ^ definitely 1.9761x faster <geometric> * 259.8404+-3.1578 ? 260.2540+-4.6407 ^ 77.1420+-1.2083 ^ definitely 3.3683x faster <harmonic> 235.1094+-4.3063 ? 235.9726+-5.2733 ^ 47.9006+-0.2729 ^ definitely 4.9083x faster

Caused jscore test failures? http://build.webkit.org/builders/Apple%20MountainLion%20Debug%20WK1%20%28Tests%29/builds/13373/steps/jscore-test/logs/stdio

I saw a one-off timeout like that but never reproduced it. I will skip the test and investigate. You can skip a JSC test by putting "//@ skip" at the top of it.

The test times out fairly consistently under Debug DRT on my MBP
