I don't think so. Because I tried one thing a few minutes ago. I opened 4 ssh channel and run rsync command and copy bigfile to different targets in cephfs at the same time. Then i looked into network graphs and i see numbers up to 1.09 gb/s. But why single copy/rsync cannot exceed 200mb/s? What prevents it im really wonder this.

I think it is still slow :/ Is this an expected? Perhaps that is the bandwidth limit of your local device rsync is reading from? -- Patrick Donnelly _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
