Hi Sergei,

I just realized that I didn't share benchmark results (read-only OLTP that XL did): 5.6 tps: ~18k 10.0 tps: ~9k 10.0 + MDEV-4956 tps: ~11k

I estimate tc_acquire_table and tc_release_table are eating up ~6k tps (2k per list).

Wasn't this difference caused by LOCK_plugin? -- Patryk Pomykalski
