Read more at Performance Enhancements in the Next Generation TCP/IP Stack.
Vista is not optimised by default. The commands to enable the next generation IP stack features are: netsh interface tcp set global ecncapability=enabled netsh interface tcp set global congestionprovider=ctcp Please add this important info. to your Vista FAQ!
Please read http://en.wikipedia.org/wiki/Windows_Vista_networking_technologies
DrTCP does indeed work. As previously stated it will allow you to select from all your different network interface devices. I do not reccomend changing the MTU.
Bunk! Routers that don't know about ECN can still drop packets normally, but there is some ECN-hostile network equipment on the Internet. For this reason, ECN is disabled. Compound TCP is a modified TCP congestion avoidance algorithm, meant to improve networking performance in all applications. It is not enabled by default in the pre-Service Pack 1 version of Windows Vista, but enabled in SP1 and Windows Server 2008. It uses a different algorithm to modify the congestion window - borrowing from TCP Vegas and TCP New Reno. For every acknowledgement received, it increases the congestion window more aggressively, thus reaching the peak throughput much faster, increasing overall throughput. Install SP1 for Vista.
I beg to differ about drtcp not supported with vista,I tried the app.and changed the tcp recieve window values to various settings and each one had an effect! I used suggested tweak settings from dslreports.com after providing my info. needed to see if my settings were adjustable even after reading that vista tcp stack settings were optimized at default values,(255500 being default)and setting the value to 65535.So I would suggest ONLY tweaking tcp receive window settings.(I might need to add that I had a choice between ethernet and wifi card sett. on a laptop,I was using the ethernet for an isdn provider.) from: email@example.com
