> Recently I did some performance tests on kubemark cluster with 1k hollow nodes, and found the recovery phase will take almost 1 minute, querying pods on specified node one by one is the most time-consuming logic inside. Therefore I propose to query all pods once here to improve the recovery performance, after this improvement, the cost time of recovery phase can reduce to only 2 seconds.
