Network Throttling in Windows
by Bill on Dec.09, 2009, under Networking, Windows
With a little more reading, I ran across this in Microsoft’s Knowledgebase: The article is for Windows Vista, but it applies to Windows 7 as well. Basically, Microsoft throttles network trafffic to give better network performance to Multimedia apps…i.e. streaming video, etc. Read the article and then make the twek as you see fit. I set mine to 70 with no issues. Very noticable network performance changes. No reboot needed, but with Windows, it never hurts!
