PimpMyOSX is a easy to use Mac application that makes your network connections faster. How does it do it? It optimizes the OSX network performance by tuning kernel parameters to match your network environment.
One selects a network type such as cable modem, telephone dial up, DSL, etc. then PimpMyOSX makes the adjustment. If the computer is rebooted, the settings remain in place. That's it! A 20% or more performance INCREASE can be expected!
The performance adjustments are performed On the Fly. Adjustments are made to BSD kernel networking tunable (and other OS) parameters. What's New
Version 1.4 - Changed some of the parameters to take into account the fact that maximum socket buffer size in Mac OS X is limited by the available system RAM. Requirements
