Hi All,

If you are interested to increase your broadband pergorance, then try out Apple Broadband Tuner 1.0
http://www.apple.com/support/downloads/broadbandtuner10.html

Info from the site - 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.

        The system parameters are sysctl variables that are set as follows:
        net.inet.tcp.sendspace: 131072
        net.inet.tcp.recvspace: 358400
        kern.ipc.maxsockbuf: 512000

Cheers,
Peder
