Subject: Investigate busy ceph-msgr worker thread
Date: Thu, 3 Dec 2020 12:01:00 +0100	[thread overview]
Message-ID: <9afdb763-4cf6-3477-bd32-762840c0c0a5@bit.nl> (raw)

Hi,

We have a cephfs linux kernel (5.4.0-53-generic) workload (rsync) that 
seems to be limited by a single ceph-msgr thread (doing close to 100% 
cpu). We would like to investigate what this thread is so busy with. 
What would be the easiest way to do this? On a related note: what would 
be the best way to scale cephfs client performance for a single process 
(if at all possible)?

Thanks for any pointers.

Gr. Stefan
