Proving Gig Speed

Here I have from my notebook
right now. It is i5-2540M CPU.

First of all, NIC is much more important than CPU. Intel NIC can give
1Gbps easy, while Realtek or Broadcom probably never gives you more than

Linux times faster than Windows in the same hardware config. Speedtest
very dependent on the browser, so try different and find better with
your configuration as well.

Sometimes you will need to tune TCP stack options to have >100mbps in
one TCP session.

Speedtest usually shows good results on download, but somewhy shows slow
upload speed. Nowdays it is better, but several years ago I can't get
more than 100mbps upload in same configuration of notebook and network I
have now. Real uploads was on gig speeds.

But the best is to use IPERF to do meansurements. It is really accurate.

All our techs have Dell laptops of various models, but we always hit 100% CPU when doing a Ookla speedtest for a server we have on site. So then if you have a customer paying for 600M or 1000M symmetric, they get mad and demand you prove it's full speed. At that point we have to roll out different people with JDSU's to test and prove it's functional where a Ookla result would substitute fine if we didn't have crummy laptops possibly. Even though from what I can see on some google results, we exceed the standards several providers call for.
