I've just fixed the (now ancient) FMS bandwidth tester. It's based on some pretty old code by Adobe engineer Pritham Shetty and wasn't working since I rebranded the blog - well now it's functional again and I plan to connect it to a new server soon.
The neat thing about this FMS app is that it checks bandwidth both to and from the server - this is very useful if you build RTC based apps that utilise things such as webcam video or live audio.
If right now the speed results seem low then that's probably due to the very old machine I'm using to host the app... Believe it or not, the server is still the same one from back in 2005!
