[chromeos-chrome] Merging field profile with benchmark profiles for AFDO |
||||||||||||||||||||||
Issue descriptionThis bug is used to track our effort of moving from field profile to benchmark profiles for AFDO. Right now, chromeos-chrome is using field profiling for AFDO profile. We can see if benchmark-based profile, or some sort of combining the two profiles can bring performance benefit.
