Mac OS X 10.4 Tiger, Apple’s Broadband Tuner
Released in November 2005, Apple’s Broadband Tuner 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.
Download Broadband Tuner and the installer will do the rest. Broadband Tuner is not an application so it will not appear in your Finder. In essence it changes default parameters coded within your Mac OS X 10.4 operating system. An optional uninstaller is also included to revert to Mac OS X 10.4’s factory settings.
A great tweak for the rest of us who want to squeeze every ounce of bandwidth through our broadband connections.
