Perf-improve tracking for r596492 "Make ObserverList 10~20 times faster" |
||
Issue descriptionDumping ground for pinpoints tracking perf changes around r596492. i.e. https://chromeperf.appspot.com/group_report?rev=59649 This is difficult because of Issue 894287 "rendering benchmark results is noisy" There are 1016+25+8+59+16+6+37+5+4+3+51+5+3+2+1+1+5+1+2+1+3+2 = 1256 items in that group. That first blob is rendering.desktop Hm. And a lot of the other stuff is Issue 892685 . I dunno if I can get useful stuff out of this experiment. I'll do some spot checks.

😿 Pinpoint job stopped with an error. https://pinpoint-dot-chromeperf.appspot.com/job/14e682e6e40000 All of the runs failed. The most common error (330/800 runs) was: ReadValueError: Could not find values matching: {'story': u'https://www.google.com/calendar/', 'histogram': u'LevelDB_memory_dump_cpu_overhead'} |
