noooooooo, speedguide blows.
Go to
DSLReports and at the top of the page choose to jump to RWIN. This will explain the only tweak that really does anything for broadband. The pluses are more throughput, but there are consequences if you have a good amount of packet loss or if you play a lot of online games. Basically, it adjusts the amount of data that is sent through before a packet is returned saying that the data was received ok.
Read the article, it will explain it better than I can at 4 in the morning.
And if anyone is wondering why I dislike speedgquide, it is because they more or less just tell you what to adjust without much of an explanation why, and they like to adjust things such as blackhole detection and MTU, which have no effect on broadband performance and can actually cripple it.
