Re: Measuring bandwidth, bad packets, latency

[Tal Bar-Or <tbaror () gmail com>]

Hi
if you using windows for testing i suggest
Ntttcp<http://www.microsoft.com/whdc/device/network/tcp_tool.mspx>this
util will test and report throughput but also lots of hardware NIC
info
if you are using Linux i suggest using
IPERF<http://sourceforge.net/projects/iperf/>this util will report
also throughputbut for hardware NIC  info you will
need to use wireshark 802.3 info to check if are errors

Regards
