[Gluster-users] GlusterFS performance

[Явор Маринов]

I've made a mistake we are using 30Mbit connectivity on all of the 
nodes. Below is a iperf test between the node and the client

[root at gfs4 ~]# iperf -c 93.123.32.41
------------------------------------------------------------
Client connecting to 93.123.32.41, TCP port 5001
TCP window size: 23.2 KByte (default)
------------------------------------------------------------
[  3] local 93.123.32.44 port 49838 connected with 93.123.32.41 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.1 sec  49.9 MBytes  41.5 Mbits/sec
[root at gfs4 ~]#

But when trying to copy a 1Gb file on the client's mounted volume the 
speed between the client and the node is ~500kb/s
