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...

A modest application, at an immodest price.

Don't fall for this overpriced one trick pony. Cocktail will tweak your network settings, along with a whole lot more, for a truly modest price. MacPilot also will, but it doesn't offer any presets, so you've got to know what you're doing. But if you're messing with these settings, it's best if you at least have an idea of what you're doing.

This application hurt network performance overall, and didn't restore my system to its previous (better) performance when I asked it to return to the defaults.

I have a cable modem connection that gets me 6 Mbits/second over a wired connection to nearby internet servers, and I was interested in seeing if I could improve download speeds from distant servers. After applying the presets for "Cable Modem", I began getting only 4 Mbits/second from the same nearby servers -- a 33% DECREASE in speed. After asking it to restore the defaults, I started getting less than 3 Mbits/second -- a 50% decrease from vanilla Mac OS X. And it's a little disturbing that when I asked it to turn itself off, instead what I got was further slowing of the connection.

A nice idea, not ready for prime time.

An already superfast cable connection made even faster by this app. And that's without any advanced tweaking. I'm impressed!

For Pete's sake...I even tried to download from the author's site and was told that their FTP server is not recognized by my situation. I have NEVER gotten a message like this ever! Now I am cannot take teh day and test this out because I can't even download it and it's something that might really help me. Bah!

After I updated this from v1.6c2 to v1.6c3, it wouldn't start up from login item. Don't tell me that I have to pay for the update since I paid for the v1.6c2

Very disappointing.

I'd love to hear from your directly if you have trouble getting IPNetTunerX to work as a Login Item. Version 1.6c4 writes to the system.log (view with Console.app) to show what settings are applied relative to other network startup events.

Wonderful--I AM having trouble with my internet connection here in ISTANBUL. SO I tried to download the thing and safari tells me they can't down from this location. So how does one review something that's supposed to help smooth out a connection when the connection is refused? That's the first time I haven't been able to have the system at least attempt to download.

We use ADSL here. Pretty lame, but some folks make it work...

Honestly, I didn't really notice any difference. I checked the defaults versus the adds for the default cable modem setting. Not much change really. Hardly worth mentioning, but for a person interested in a GUI interface to manually change I suppose the program could have some value.

Sorry, it's a question
Is there any point in getting this if you're not exactly the smartest person when it come to IPs and proxies and all that jazz?
How easy is it to use?

This is a great product. I installed and adjusted MTU in OSX 10.2.6 in seconds and solved a problem plaguing me for over a week.

My Asante FR3004C DSL router stopped working correctly on 8/13/03. I noticed I could not upload or download files to my Linux web server. I use Macs in my office. My ISP/DSL provider is Windows-based. After checking all cables and equipment, I determined the router needed adjusting. Asante tech support forum helpful, but gave me incredibly difficult solution the first time around. Both Verizon and Asante suggested MTU setting change. Apple's instructions on how to do this are more than I want to mess with. Other forums suggest it is a multi-platform issue related to Lovesan worm infecting Wintel machines.

FYI: I also read this solved connection issue through Linksys router too.
