i have the "MSI i-Speeder" utility that come bundled with my MSI motherboard click here. as expected, it is designed for exclusive usage with MSI motherboards only. so far, i have not bothered to explore into the details. maybe someone with MSI motherboards can advise if it is a useful utility or not.
back to your specific request, i know of this (similarly-named) shareware "iSpeed" from High Mountain Software click here which you might want to try.
internet speed enhancement is also an integral feature of the well-known shareware "System Mechanic" from iolo Technologies click here.
i believe some people here should be able to provide useful insights on the relevance of internet acceleration tools.
