All the failures are on FYI bots. I'm trying to figure out if there's any way to run a bisect on them.

For some reason, this regression only shows on the FYI bot: https://chromeperf.appspot.com/report?sid=3f389feec328b24de1319b621fd8b76e4feaa81d7d2f98c7af7d91745c5f036a&start_rev=402079&end_rev=404911

This is a regression on FYI bot(s), for which we currently don't have bisects. Therefore, we agreed to not track Memory System Health benchmarks on FYI bots anymore (https://github.com/catapult-project/catapult/issues/2482).
