is a simple application that allows you to optimize your Mac's Internet
performance. IPNetTuner supports over 30 adjustable parameters including
the TCP Window Size, Time Out intervals, Maximum Segment Size, and
MTU. It also provides a convenient test tool so that you can immediately
see the results after adjusting specific parameters (or opening
one of our preconfigured tune up documents). Users typically report
speed increases of between 10 - 50% using IPNetTuner.
Why might you need IPNetTuner? Open Transport's default settings
must enable connections for both slow analog modems as well as very
high-speed ethernet connections. As such, these default settings
are not optimized for either type of connection (although they do
let both types of connections to work). To get the most out of a
specific type of connection you really want to setup Open Transport
so that its internal settings best match that of your network connection.
This is where IPNetTuner comes in....to assist you in tweaking these
Open Transport settings.
Actual tuning example for cable modem connection. Graph
shows throughput downloading a 45 KByte page from cnn.com. Lower
values are without tuning (~110 KB/s) , upper values are with tuning
(~175 KB/s). Tuning results in approx 60% increase in throughput.
We even assist you with this by supplying you some pre-configured
IPNetTuner documents for both slow and high-speed network connections.
All you need to do is double click the appropriate document and
Open Transport is automatically configured for your chosen network
connection type. That easy.
Once the desired parameters are set, you can quit IPNetTuner. IPNetTuner
simply changes the internal settings within Open Transport. These
settings remain in effect until you either restart the machine or
make new changes to these settings.
Additionally, IPNetTuner documents can be saved as an "Auto
Configure" document. You can simply double click such a document
or put it in your Startup Items folder and IPNetTuner will launch,
load the saved settings, configure Open Transport, and then automatically
