I'm surprised that's all you found on a college LAN. I'd say the smartest thing to do (as if this is ever done with college networks) is just to disable your file-shares/NetBIOS and live life wonderfully at your co-op. I HIGHLY doubt that *uncapping* file does anything but occupy hard-disk space ...

I just want to say that the desk in the picture is abnormally clean and looks like "someone" may have suspicously cleaned it before the image was taken...

Anyway, you got all the things you love in one frame on the picture so good job!

Ah yes folding@home, the "search" for well protein interaction I suppose.

Anyway, Lance does alot of good work folding. I'm adding my 3.0Ghz P4 to the mix, and to the Speedguide team.

Yeah I had it on the SG template all along, and just noticed the dark theme. I need to get some going for BBNUTS now

Latency is really all dependant on your connection medium, setting the TCP buffer is really just making sure it is set to a connection specific number.

Most games as you know use the UDP protocol. TCP/IP tweaks like mine, or Speedguides only tweak TCP protocol specific registry values, so UDP would ...

Great vBulletin template

Man I had it stuck on the old template forever, and I now just changed my options. I know how anonying it is to get all the colors right. Good job Philip

Matches the navigation menu even. It was easy for me just used the convert script.

Thanks, I was rebooting the server without closing the board first, that's why you got the message.

Thanks for the feedback

I wish I could do that. When MySql fails I have to call the tech

The Netgear FA310/FA311/FA312 are probably the best price/performance cards out there. In LAN speed testing where a ethernet card really shows it's true colors the Netgear attains one of the fastest results.

AFD 'afd.sys' would be the Ancillary Function Driver. This is the Kernel mode control system for Winsock. Winsock is a widley used programming API built on top of TCP/UDP. Such things as FTP, and HTTP both use Winsock API calls.

Hello

by cablenut

Yes rmrucker I agree that is why in my post on my discussion board. I picked places where I knew I had many hops too (i.e. german sites, and canadian sites) I then took my Max latency and my Min from that group of sites and averaged them out. I wouldn't suggest finding your RTT from sites where you ...

Your RWIN is a total factor of your Connection Speed & Latency across your connection.

RWIN Discussion

The end users system really doesn't matter per say, as long it is optimal enough to accept the Internet connection to 100% it should be fine.

Glad to see some comments about it. If you want to talk about it more come on over to the CableNut Software discussion board.

Packet Loss has mostly to do with Load on the various IP gateways, and Latency.

Load
If a router is heavily loaded with TCP packets your packet might get discarded from the routers queue i.e. packet loss.

Latency
If the latency to the server machine is high you have to expect a high retransmission ...

Cablebumbs "treat"

All right guys this is getting out of hand. First of all I would like to say I see no viable problem with someone posting, distributing, or talking about a .CCS tweak they have made. There are some legality issues if you use one of my .CCS files for those purposes I mentioned above. It looks if ...

Excellent!

Sadly the FA311 does not support 802.1P, neither does the ,FA310/FA312. The Intel 100+ Management 8460b chipset ethernet card supports 802.1P Quality of Service.

This does not work for Windows 2000, I have found no way other than restarting the system. The problem lies in the fact the tcpip stack must be stopped and started again to re-read the registry settings. When you log-off it does not stop the tcpip service, when you kill explorer you are killing the ...

To turn timestamps off set Tcp1323Opts to "1" or "0"

I would use 64240 (MSS x 44) because if you used the bigger ones they would be scaled down to 64240 anyway.

by cablenut

To use RWIN over 64240 you have to set Tcp1323Opts to "1" however most servers don't allow RWIN over 64240 so they scale any window over that down.

The follorwing RWIN are optimal:

513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2 ...

by cablenut

Turn timestamps off and use one of the following RWIN:

513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

Looks Ok Now

by cablenut

Using a 500kB file is useless for accuracy. You need a much bigger file (5MB of over) to get a true reading. The reason verizon is using a small(er) test file most likely is to fool its users thinking they have more speed than what they actually have.

Most games use the UDP protocol to allow online play. RWIN'S and such don't matter because these are TCP protocol options we tweak.

Since 99% of the time your big bad RWIN over 64240 isn't being used any one of the below RWIN's would be optimal:

128128 (MSS x 44 * scale factor of 2)
64064 (MSS x ...

by cablenut

"If you enter a RWIN of 642400, you're scaling will be at 4. Probably not worth it... Lots of packet loss"

THis is a misconception amoung alot of people. First of all we can't test our RWIN's with ping because ping uses ICMP which does not use TCP options or RWIN's. Second 99% of the time any RWIN ...
