Well, It really depends. We found them to be extremely inconsistent. We actually host a speedtest.net server just for this reason.
We found on very fast connections (Like.. 100Mb/s and above) that they are completely inaccurate. Where is on normal connections (10-30Mb/s) they seem to be pretty close. We take iperf (Or mikrotik speedtest) results over all else. That being said, We generally find when the site based speed tests are extremely low for multiple users there is normally a problem. Even if its hard to see at first. Have this customer test to a few different locations. Then let him download a large zip file from your own network (Like a webserver off your BGP edge routers) and compare.

We mostly deal with business customer and guarantee bandwidth to customers. We validate the bandwidth using IPERF from a Linux server off of our BGP edge routers down to the customer and IPERF always shows the customer getting the bandwidth they signed up for. We use QoS to control bandwidth and make sure to not oversubscribe any one link....small ratios of 3:1. Of course eventually at some point the customer runs one of those stupid bandwidth test on the Internet and the results are woefully inaccurate (not in our favor)...but of course customers take the results as gospel. AAARRRRGGGGHHHH! It's not our internet connections, we have three 100Mbps BGP links and none of them run at more then 50% during peak loads. Has anyone else found those Internet speed test to be woefully inaccurate? Or is something else going on that I'm missing? Thanks, Bret
