I'm assuming you're testing the speed of cephfs (the file system) and not ceph "object storage".
In my recent experience the primary thing that sped cephfs up was turning on striping. That way the client should be able to pull down data from all 10 nodes at once, and writes should, also, be written in parallel as well. Setting the various cache, stripe, etc sizes is particularly important and depends heavily on the type of load you are testing. -----Original Message----- From: ceph-users [mailto:[email protected]] On Behalf Of Udo Lembke Sent: Wednesday, June 25, 2014 7:09 AM To: [email protected] Subject: Re: [ceph-users] How to improve performance of ceph objcect storage cluster Hi, I am also searching for tuning the single thread performance.
