When the ceph client reads a very hot little file (less than 4M). The application scenario is live video. A single disk may have a bottleneck. The ceph client only reads the primary pg of osd. But this is the implementation of the serial. My suggestion is to change the primary read to random read three replication, or change to read 3 replications at the same time, so to improve the reading efficiency. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
