[Gluster-users] increase write performance in gfs 3.5.2

I'm new to glusterfs and I dont understand 'the 
performance.write-behind-window-size' option. I'm using glusterfs 3.5.2 
and setup a volume over two nodes connected over 1 GbE.
Actually the write performance is about 58 Mb/s. This means glusterfs 
writes the data simultaneous on both nodes. I'm trying to increase the 
write speed and I thought this option would cache the data
on one node and then distribute to the other. So i could double the 
speed. I played around with this option, but it has no effect to the 
write speed.
What am I doing wrong or is there another tweak to increase the write 
speed ?

Thank you
