it has some basic settings files but it is always best to find your own optimal values. That is where most of the other apps fail, they try a one size fits all approach when that is never the case.
btw DSLreports and DrTCP are the worst in this line, the speedguide optimizer is OK but still lacks the functionality of cablenut. The only good thing I've seen from the DSLR tweak tester is the retransmission report, everything else can be ignored. They have no idea over there, really.
As far as pretty much optimized for Broadband, well thats just plain wrong, the default AFD buffers in XP are still configured for a PC with 8MB of RAM. They haven't changed since 95.
