Subject: Performance improvement with 58a2e3f5c37be02dac3086b81bdda9414b931edf

[-- Attachment #1.1.1: Type: text/plain, Size: 617 bytes --]

Hello Stefan, folks,

the perf-ci detected and bisected the 58a2e3f5c37 - block: compile out assert_bdrv_graph_readable() by default - as a performance improvement especially with 4K reads with multiple jobs (but minor improvements were observed in other variants)

    https://ldoktor.github.io/tmp/RedHat-virtlab722/v8.0.0/140-improvement.html

Based on the commit message I guess it's expected so take this just as a record of improvement.

Regards,
Lukáš
