cable modem users info - MaxMTU setting, etc

Ive spent the last few hours lurking around the net, looking for information about cable modems, specifically looking for recommended registry settings (ie: MaxMTU, DefaultRcvWindow, etc) to increase people getting much higher download speeds than I so I thought I would try tweaking my registry settings to see what kind of performance boost I could get. A good site I found was [link lost in import] They have some patches and links to programs like EasyMTU, TweakDun that will change your settings for you. Instead of having to backup my registry and using their Generic Registry Patch for Windos 98, I chose to use EasyMTU and implement a few of their "Recommended settings for Windows 98" from within EasyMTU. I changed the MaxMTU to 1500, DefaultTTL to 128, and DefaultRcvWindow="372300", rebooted and fired up my browser. I tested the new settings on a 40mb download ad noticed a HUGE improvement. I was getting about 660kbps after the changes from my old regular speed of about 60-80kbps (on average) (depends on site too. This was a demo download from download.com) I believe the improvement has alot to do with the DefaultRcvWindow value of 372300 because now my connection is requesting more data at a given time. The only problem with this is the packet loss factor. With a high DefaultRcvWindow value, if a packet is lost, the packet size is much larger (from what i have read). I havent tried an online race yet with these registry settings and plan to once i am done here, but I am assuming the DefaultRcvWindow value of 372300 may not be so good for online racing. If i lose a packet it will be a large packet and could makethings worse than the settings I had (which was win98 default) A lower DefaultRcvWindow value will probably work better for online *** I was wondering what kind of registry settings other cable modem racers out there are using in order to improve their online racing experience. What would the "best" settings for online racing to help keep a more stable connection while reducing warps? anyone? :) I will give my settings a try and see how it goes. I wasnt disappointed with the default win98 settings and my online connection while racing,but thought I would try to Improve it if i could. Anyone out there mess with their registry settings (cable modem users)? Have you come across an excellent setting you can pass on to others? BTW, check out this story "Get a Cable Modem......Go to Jail" [link lost in import] subscriber worth reading.... Also, check out the bandwidth speed test at: [link lost in import] According to my test,my line speed is 1854.5 kbps or 227.3 kbytes/s which is between the range of a T-1 to T-2 line. :/ Chow...

I am also on cable, and have played with several registry tweaks. As the host of a N3 league, I have found that with the tweaks many of the guys were experiencing more frequent clock zaps than before. I think that your suspicions are correct, in that larger packets are bad for on line ***. I have recently gone back to the default settings, and the connections are more stable in the league races. You may get faster downloads with the tweaks, but if you are hosting on-line races, it's not worth the problems it creates. -Paul Western States Racing League: http://www.members.home.net/helipaul/n3.htm My reply address is false.

For GPL, MaxMTU and DefaultRcvWindow are not important. The largest packet GPL will send is 340 bytes or so (130 bytes with the usual core.ini settings). This is less than the mininum for MaxMTU. And DefaultRcvWindow is part of TCP, but GPL uses UDP. Bart Westra www.xs4all.nl/~westrab/gpl.htm

Do u use win98 Kevin? MTUSpeed requirements doesnt have win98 listed and ive had problems with programs that are not win98 compatible in the past. Is the win95 compatible version ok for win98? U use those settings for racing? how is it? Rwin of 10? thats pretty low, arent your download speeds really slow with a value of 10? mine would be Skotty Flynn http://www.nascar-racing-sims.com (webmaster) "skotty" on WON

>Clear your history and disk cache. Funny thing is. I've run this a half a dozen times now and the only time I've been "off the chart" was the first time. I'm consistently around 2500Kbps now.

I have tried my new settings a fair bit now with N3. Mostly on the oscarSrv. While these settings are great for fast downloads, it wasnt working the best for online racing. MANY clock zaps and bad connection messages. I went back to default settings and things cleared up. I still think there is a setting which could speed up downloads while still providing a good racing connection, its just a matter of finding it. Someone else must have found a good setting by now, just wish they would read this. :) On Thu, 18 Nov 1999 09:59:57 GMT, skotty
