About
throttled is a bandwidth shaping application for Mac OS X and FreeBSD which allows you to cap your upstream bandwidth, prioritize ACK packets, and keep your download speeds high even when your server is sending out at full speed.

Features
* Allows you to set a global bandwidth cap for all your applications, or multiple caps with different speeds to guarantee all your servers a certain amount of bandwidth.
* Allows you to setup wighted queues for your network data to guarantee low-latency ssh, telnet, etc connections on your server.
* Includes optimizations for many online games including Unreal Tournament 2004, World of Warcraft, Call of Duty, Ghost Recon, Starcraft, Warcraft II, Warcraft III, and Diablo II.
* Prioritizes TCP ACK packets to allow consistent bandwidth in both directions even under heavy server load.
* It uses almost no resources. CPU usage is around 0 - 3% and it uses less than 500k of RAM.
* Source code is freely available, and released under the GPL. Please read the COPYING file in the distribution.

The default rule setup has changed, so please read the included docs and comments in throttled-startup. We have also been preparing a gui release that should be out in the next few weeks, so check back with us soon.

07/06/03 - throttled 0.2.9 is now out. If you haven't updated your copy of throttled in a while you should definitely check out this release. throttled now catches all file transfers without any configuration thanks to a new ipfw rule style from the minds of wincent.org. We also included more documentation in throttled-startup and have updated the ipfw rule cleanup so it is more reliable and doesn't require perl.

06/11/03 - throttled 0.2.8 is now available. We have been preparing for our first gui release and finally have throttled cleaning up its own ipfw rules (Thanks DocGonzo). Keep a lookout for throttled Pro coming out in the next few months with a cocoa interface.

07/06/02 - throttled 0.2.5 is now available. This version adjusts its priority to increase performance under heavy CPU load. If you download the source, you should look at throttled.h and adjust any of the defines to your needs. In addition, a few compiler optimizations were added, and throttledStartup was updated to work with dynamic ip address' (Thanks Thierry).
