01/05/2022 perf meeting is on!

Hi Folks, Happy New Year!  The weekly performance meeting will be starting in approximately 5 minutes at 8AM PST. The etherpad appears to be broken so I wasn't able to properly review updated PRs, but it looks like there hasn't been a ton of movement since we last met in December. I looked at new/closed PRs for the last ~3 weeks, but might have some overlaps with previous updates since I can't see the etherpad: New PRs: https://github.com/ceph/ceph/pull/49482 (mClock: Add ability to handle high priority operations, amathura) <-- Ronen and Sseshasa review https://github.com/ceph/ceph/pull/49438 (os/bluestore: set rocksdb iterator bounds for Bluestore::_collection_list(), cfsnyder) <-- ifed01 reviews Closed PRs: https://github.com/ceph/ceph/pull/48566 (os/bluestore: Fix race condition in Onode:put(), taodd) <-- closed in favor of 47702 https://github.com/ceph/ceph/pull/48226 (osd: Reduce backfill/recovery default limits for mClock and other optimizations, sseshasa) <-- merged to main by Neha Bluejeans: https://bluejeans.com/908675367 Mark
