Summary Bencher script doesn't measure GC times accurately
Filip Pizlo
Reported 2011-10-21 01:32:18 PDT
The bencher script runs benchmarks using the SunSpider harness style, where gc() is invoked between samples. This means that GC times tend to not be measured. But particularly SunSpider and V8 have significant GC pressure when run repeatedly. The bencher script should retain its default mode (since it's great for pinpointing performance changes in the mutator) but have options to also measure GC times.
