I'm testing iozone inside a VM booted from a gluster volume. By looking at network traffic on the host (the one connected to the gluster storage) I can see that a simple iozone -w -c -e -i 0 -+n -C -r 64k -s 1g -t 1 -F /tmp/gluster.ioz will make about 1200mbit/s on a bonded dual gigabit nic (probably, with a bad bonding mode configured) fio returns about 50000kB/s, that are 400000 kbps. As I'm using replica 3, the host has to write to 3 storage server, thus: 400000*3 = 1200000 kbps If I understood properly, i'm able to reach about 1200000 kpbs on network side, with sequential writes, right ? Why a simple "dd" will return only 30MB/s ? _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://lists.gluster.org/mailman/listinfo/gluster-users
