Hi @SzyWilliam, we found some performance degradation in our Ozone cluster when we set `purge.preservation.log.num` (introduced in RATIS-1626) to a large number. The reason we set it quite high is to prevent follower to install snapshot from leader by downloading the leader's large DB. I suspect that causes a large number of close segments preserved which causes the `evictCache` to take a long time since it has to go through the closed segments twice. -- This is an automated message from the Apache Git Service.
