Final sys-perf patch build is here, which includes that commit that removed the feature flag as well as SERVER-44334 from above. Note that the base commit also includes the feature flag removal, so its best to compare against an older commit (e.g. 1f5591c7a060cc9a048462b618e2ca7c767036c3 for standalone). To summarize the results:

AFAIK, these results include any relevant perf fixes from the "Unity projection implementation" project as well as any perf improvements from the M/R in agg project. Mostly posting the numbers for posterity as we don't plan to spend any additional time on this as part of PM-766.
