Apple Broadband Tuner – Free Speed!

December 1, 2005

I kind of had my doubts about the new Apple Broadband Tuner — I’ve seen a lot of this type of thing over the years (mostly on Windows systems), but few of them made any noticable improvements, and some of them caused a rash of problems.

I’ve been playing with it on my FIOS line for the last couple of days, however, and I can say that it makes a vast difference on some stuff — particularly loading web pages that have a lot of connections to different objects, like pages full of images, etc. Even better, I’ve noticed no complications with anything, either.

If you are a Mac user on a relatively high speed connection (Cable, Fiber, etc.), it’s worth taking a minute or two and downloading this to give it a try. It’s free, and there’s an uninstaller if you decide it isn’t worthwhile.


The Broadband Tuner allows you to take full advantage of very high speed FiOS based Internet connections that have a high latency. The installer tweaks some system parameters.

There is an optional uninstaller that can be used to restore the settings that were in effect at the time just before the system parameters were changed.

What does the Broadband Tuner do exactly?

The installer increases the default values for the size of the TCP send and receive buffers. With larger buffers more data can be in transit at once. A startup configuration file is also updated so that these changes will persist across restarts.
