Any advice would be greatly appreciated. > Andrew, 300 MB/s for sequential write is reasonable expectation for replicated writes with 10-GbE. You shouldn't need the volume parameters. Make sure you don't have a CPU bottleneck, I'm not sure what speed CPUs you have, use "top", press H, see if any thread in glusterfs (client) or glusterfsd(server) hits 100% either on client or server. Try single replica to see if the problem is replication-related or something else. If it's related to replication, you can try setting "gluster volume set your-volume performance.eager-lock on" (remount afterwards). Consider Red Hat Storage if you want a solution that is pre-tuned, performance-tested and supported by Red Hat. -- Ben England, Red Hat _______________________________________________ Gluster-users mailing list [email protected] http://supercolony.gluster.org/mailman/listinfo/gluster-users
