I queued this up last night but didn't realize tip:sched/core had moved
since my last run so my baseline numbers might inaccurate for
comparison. Please give me one more day and I'll get back to you by
tomorrow after rerunning the baseline.

P.S. I saw a crash towards the end of my test run (might be unrelated)
I'll check on this too and get back to you.
