IPNetTunerX is a modest application that allows you to optimize TCP/IP network performance under Mac OS X by tuning internal TCP/IP parameters to match your network environment. IPNetTunerX supports over 50 adjustable parameters including the TCP Window Size, Time Out intervals, Maximum Segment Size, and MTU.

Beyond adjusting parameters, IPNetTunerX provides tools for measuring the effect of your changes, and a Location Helper to make dynamic configuration easier.

Use our preconfigured settings for most common types of Internet connections. Or you can adjust your settings and save them in IPNetTunerX settings more...
