Hi Lindsay, thanks for your information and comment.> Hi Stefan, a bit more information on your setup would be useful > - Brick topology - replica 3? distributed? >yes, replica 3.

Ideally they would be LACP bonded with a switch that supports LACP. Even so, you would get a max of 1G between individual nodes. Couple of tests you can do. - Monitor network load while copying a large file onto the gluster mount using iftop on the node where the copy is happening: iftop -i <network port> Where network port is the card (eth0 etc) or the bond/bridge That will dynamically show the load between nodes. - use iperf to test your raw network speed: http://openmaniak.com/iperf.php Hope this helps -- Lindsay -------------- next part -------------- An HTML attachment was scrubbed...
