Ganesh-induced Performance Regressions

Project Member Reported by bsheedy@chromium.org, Nov 14 2017 
The introduction of Ganesh introduced a fairly large memory regression, e.g. https://chromeperf.appspot.com/group_report?keys=agxzfmNocm9tZXBlcmZyFAsSB0Fub21hbHkYgIDgj5CttQoM. This has been largely alleviated by a subsequent fix that linked Ganesh to the correct GL interface, but it's still ~1MB higher than it was previously.

The regression appears to be solely in the memory:chrome:all_processes:reported_by_chrome:malloc:effective_size_avg measurement.

This also appears to affect memory:chrome:all_processes:reported_by_os:gpu_memory:proportional_resident_size_avg and memory:chrome:all_processes:reported_by_os:gpu_memory:gl:proportional_resident_size_avg, see https://chromeperf.appspot.com/group_report?keys=agxzfmNocm9tZXBlcmZyFAsSB0Fub21hbHkYgIDgr96LswkM

However, the most recent run seems to have returned to normal for those two measurements, so it may have been inadvertently fixed.

Summary: Ganesh-induced Performance Regressions (was: Ganesh-induced Memory Regression)
It seems that the memory regression went away. However, we now see a small regression in text rendering times: https://chromeperf.appspot.com/group_report?keys=agxzfmNocm9tZXBlcmZyFAsSB0Fub21hbHkYgIDgr96LswkM

The text rendering regression seem to have gone away too.

Closing since regression went away.
