I would like to introduce you some of tools for measuring network performance here. They are pretty simple and useful.
iperf
Iperf is a tool to measure maximum TCP bandwidth, allowing the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss.
Scott's slide about iperf.
nuttcp
nuttcp is a TCP/UDP network testing tool, much like iperf. I think it's the best such tool available, for its simplicity, ease of use, and feature set.
Netperf
Netperf is a benchmark that can be used to measure the performance of many different types of networking. It provides tests for both unidirecitonal throughput, and end-to-end latency.
TTCP
Bwping
Nettest
NetSpec
