I've put the results together below. That looks correct. I had my friend dig out the missing parts from runs I haven't posted, and do the runs it hadn't run. 128-way Ice Lake, PREEMPT_DYNAMIC production-like config: rwlock avg 0.59=C2=B5s max 330=C2=B5= s synchronize_srcu_expedited() drain avg 3.65=C2=B5s max 4383=C2=B5= s synchronize_srcu_atomic(), no fastpath avg 8.04=C2=B5s max 6034=C2=B5= s synchronize_srcu_atomic() + fastpath avg 3.59=C2=B5s max 326=C2=B5= s 192-way Granite Rapids, PREEMPT_RT production config: rwlock avg 4.4=C2=B5s max 3854=C2=B5= s synchronize_srcu_expedited() drain avg 8.6=C2=B5s max 810=C2=B5= s synchronize_srcu_atomic(), no fastpath avg 12.0=C2=B5s max 620=C2=B5= s synchronize_srcu_atomic() + fastpath avg ~3=C2=B5s max 801=C2=B5= s The max values here are noisy and can vary by 2x per (300s) run. The averages are fairly clean, and I think I have per-bucket breakdowns for all of them if you really want to dig into it. Astute readers will note that rwlock actually wins on average on the "production-like" config, that the max is in the same ballpark as the srcu_atomic+fastpath too, and wonder why we bothered... the point is not just that rwlocks are the wrong thing to use for PREEMPT_RT, but also that all we're benchmarking in the above tables is the *invalidation* not the read side, which scales a *lot* better in the SRCU model and doesn't bounce cache lines around. --=-isMiZyYAk8DuxxStIRAk Content-Type: application/pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s"
