Measure network performance with Iperf/JPerf

Iperf is open source network performance tool developed by NLANR/DAST. It measures maximum TCP and UDP bandwidth performance and reports bandwidth, delay jitter, datagram loss. (Jperf the graphical front end written in Java). So it can be used to solve speed and throughput issues.

Available for windows and Linux


Setup

Wireless throughput from Notebook

Having similar setup as before I decided to check now, how much throughput I can get from my wireless on notebook.

SETUP

RESULTS

It seems that throughput increases when notebook is running on AC, and drops when running on batteries, most probably because of the Power Saving mode.

Wireless throughput from Sony Ericsson XPERIA X8

I wanted to test the wireless throughput from my mobile device.
One tool that can do this is Iperf.

Setup

Results
Best throughput I could get was 17.4 Mbits/sec.
