Use Iperf or a similar tool to measure if the network is the bottleneck.
Note that Iperfs UDP measurement is defaulting to 1Mbit/s traffic, so read the manpage before wondering why UDP performs so very slow compared to an out-of-the-box TCP measurement.

I have 2 x dell PowerEdge servers running SLES10SP2 and both connected with two Gigabit NIC in a bond with mode-0. The switch is Dell powerconnect. While doing ftp, I am getting around 90-98MB/s for single process. If I put 2 jobs together, the total reaches around 150-160MBps. The question is, is this the maximum? Or is it limited by my disk system? I am using PERC-6E with MD1000 on one server and MD-3000 on other server. If anyone got experience in this please suggest. Jestin Paul
