As you may or may not know, Windows default TCP/IP settings can hold back ones speed with a broadband connection. It may be necessary to tweak your settings to get your optimal speeds.
Download DrTCP using the link at the top of the Optimumonline forum.
As a starting place, set your Tcp receive window to 64240. Choose your network card in the adapter settings dropdown box and set the MaxMTU for your network card to 1500.
Apply, exit and reboot.
Re-run the speed tests at the top of the forum. There is a good chance you will see a HUGE jump in speed from the default windows settings.
Those settings are the best for a good many people on OOL, but not for everyone. To try to tweak further, either read the Tweak forum FAQ and/or post for help in the Tweaks or Optimumonline forums. You probably will only see minor jumps in speed from here on out, though. Some people suggest you make keep your RWIN a multiple of 1460. I'm not sure if that actually helps or not, but it can't really hurt.
If you decide to use an RWIN>65535 and use Win95/Win98/98SE, you need to install the microsoft vtcp.386 update found here:
vtcp.386 update for Win98/98SE
vtcp.386 update for Win95
In addition, for an RWIN>65535 to be recognized, you need to turn on Windows Scaling using DrTCP or other utility.
You also might want to check for updated drivers for your NIC. In some cases, that has resulted in a speed change.
Note: Changes only are effective after a system reboot.
