[Gluster-users] iozone results

[Gandalf Corvotempesta]

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 ?
