Broadband Tuner 1.0
Apple today released , a new system utility designed to take full advantage of very high speed Internet connections that have a high latency (5 Mbps or greater). Apple's documentation says that 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....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." The file is 320KB and available directly from Apple.
