Comment 2 Wei Duan 2021-07-14 09:08:26 UTC 
I'm following JIRA issue DPTP-660 to do the pre-merge verification. Used the cluster-bot launching an env with the still open but Dev-approved PR(s).

Install cluster using cluster-bot, clusterversion is 4.5.0-0.ci.test-2021-07-14-023700-ci-ln-7c0wk6b-latest and there are 3 masters + 6 works 
Check the volume_operation_total_seconds_sum metric to get the provision interval, from the result, the volume provision is improved a lot.
one volume on 4.5.41 (withour fix):
one pv: 0.81
one volume on fixed release:
one pv: 0.61

10 volumes on 4.5.41 (withour fix):
average: 0.93
one volume on fixed release(4.5.0-0.ci.test-2021-07-14-023700-ci-ln-7c0wk6b-latest):
average: 0.64

40 volumes on 4.5.41 (withour fix):
average: 1.47
one volume on fixed release:
average: 1.04
