It seems that the new feature “save-state-resume GC filewalker” isn’t functioning as expected

Does used-space filewalker need to run immediately after a restart? As there are other processes on start as well consuming IOPS, used-space filewalker does not seem to be the most urgent one to run on start-up.

If you check your logs, you will see that it will start not immediately but with some delay.
