I used it to narrow down the problem. Common comments: you have a large number of hash collisions on your partition. It can lead to performance drop. I would recommend to use tea hash in your case. This is not default and should be specified by mkfs option "-o hash=tea_hash" when formatting a partition. Not an urgent issue, juts FYI. Thanks, Edward.
