I've also found lots of recommendations for totusoft lan speed test (lite) unfortunately only available for windows and mac os x. Also i've found you can download a mini version of ookla <a href="http://speedtest.net" target="_blank">speedtest.net</a> which can be uploaded to any web server<span style="font-size:initial;text-align:initial;line-height:initial"> which
can run PHP, <a href="http://ASP.NET" target="_blank">ASP.NET</a>, ASP or JSP</span></div>

I've used iperf before.<br>
