Hi, I'm testing cephfs to serve video files. Here is a screenshot from atop: http://img835.imageshack.us/img835/7356/cephbandwidth.png The server has 4 cores, even so only 2 kworkers are working hard, others do notting. On the webserver the concurrent connections are ~1000. Is this a ceph or kernel issue?
