Please make sure the build passes.

I think the build failed (12days ago due to dockerhub problems). I need to push new commits to address review comments so we don't need to retry the build manually (I think retry on circleci has permission requirement.)

@Aneurysm9 @mxiamxia PTAL

btw: build failed for load test the extension is not enabled, so it should be loadtest's own problem.

Force pushed same commit to rerun the CI.

From steps the CPU usage is higher than expected in load test
