Apple Broadband Tuner allows you to take full advantage of very high speed Internet connections that have a high latency (5 Mbps or faster). 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

The system parameters are sysctl variables that are set as follows:
This change has a system wide effect and is applied even if the network is not high speed connection with a high latency, with the exception of modem connections for which the system uses small default TCP buffer sizes.
Note: Broadband Tuner 1.0 is not recommended for AirPort connections.

It used to take up to 165 seconds to load. I am very picky on internet speed, but I'm very, very happy with this Apple Broadband Tuner 1.0

There are numerous freeware and shareware applications that willl perform this function; with most of them doing a FAR BETTER job.
Try freeware "maintain" [available here at MacUpdate.com]. What makes it better, you muse?
Try this: Not only does it modify more internet connection parameters, (see below); but it offers you TWO separate options. Either simply double everything or selectively double, triple, quadruple whatever parameters you select; e.g. "sendspace", etc.
I STRONGLY suggest trying "maintain" The improvement in your internet connection is but one of many benefits available employing "maintain."

This Software makes my "feeled" surfing faster... Using "BroadbandOptimizer 1.5" for years on 10.3.9 but for Tiger this App is better...

this thing just blew up my brandnew poerbook 17-inch. i had to reinstall tiger from scratch.
be cautious to back up your drive or better, clone it before trying out.
Anyone notice this? Any advice?
