I agree with that .
I have a cable modem wich can reach up to 6 MB/sec .
When I put LW on "Cable modem" it never uses my connection to its full potential

I have to edit the config file (limewire.props) and force it into UltraPeer mode to work like it should .

Then my hardware firewall still reports a 80% load against the highest spike it ever measured .
Wich was 6 MB/sec .

The speeds are all calculated wrongly in LW .
