"I love this IPerfwindows with charts, I am a Senior
Network Engineer and I rely on bandwidth measuring tools for VOIP and Data
issues every day. I have other such tools but IPerfwindows just makes my life
easier, with the real time graphs and easy setup, I can spot problems
immediately. With IPerfwindows, I am able to save my reports with ease.
"The program is working very well.
I'm testing a DOCSIS 3.0 cable modem in an 8x4 channel bonded mode.
I'm able to get ~300Mbps downstream and ~100Mbps upstream without errors."
"IPERF helped us identify network performance problems by allowing us to test connections between the Windows and Linux servers in our environment."
