Hi Bharata, I am interested to see the performance for read and writes separately. Aggregated will probably be much influenced by the read performance.
Interesting the last figures, seems quiet a significant performance gain using the QEMU-GlusterFS. See if you can get the results for read and writes separately.

Ok, here are the aggregated bandwidth numbers from a quick FIO (4 seq writes using libaio) write test: Base: 189667KB/s QEMU-GlusterFS native: 150635KB/s QEMU-GlusterFS FUSE: 43028KB/s So as you can see, native is much better than FUSE, but still doesn't match the base numbers. When I say base, it means that the guest is run directly from glusterfs brick (w/o gluster FUSE mount or using QEMU-GlusterFS native driver). > Are you using IOmeter or bonnie ? FIO at the moment. Plan to include more benchmark numbers in future. Any help here would be appreciated :) > > Seems the results with fuse and the native qemu-glusterfs are pretty similar, > am I right ? No, QEMU-GlusterFS native numbers are way better than FUSE. Let me quote the numbers from the URL I gave earlier: Base: 63076KB/s QEMU-GlusterFS native: 53609KB/s QEMU-GlusterFS FUSE: 29392KB/s Regards, Bharata. _______________________________________________ Gluster-users mailing list [email protected] http://gluster.org/cgi-bin/mailman/listinfo/gluster-users
