See how cFosSpeed "Automatic RWIN expansion" feature keeps your Internet Explorer downloads fast.
cFosSpeed will now automatically expand Windows' TCP RWIN as needed! With our new "Automatic RWIN expansion" cFosSpeed will expand the RWIN (and the matching window scaling) to a value that allows a download with full speed and a delay of 100 msec.
This makes system-wide settings of "GlobalMaxTcpWindowSize" or "TcpWindowSize" (under XP) superfluous and will keep your downloads fast even if Windows 7 "auto-tuning" feature doesn't work for you
