Ok, I will admit I was a bit skeptical when I saw that this hadn’t been updated since March 2002, but I was delightfully surprised with the results. Here are the settings I used and then I will show you the results I achieved.
TCP Review Window: 64240
Path MTU Discovery: Yes
Select your network adapter in the drop down area. (Once you select your adapter then set)
MTU: 1500
Then reboot. This is important for all the changes to fully take effect.
Quite a difference huh? These speeds were tested using Speedtest.net using the same test server for both measurements as shown in the image.
