If you use wshaper to get better pings, that will not lead to overall 
better TCP/IP performance (well, it does...sometimes). You have to 
manually priorize the ports that are used by your online game.
Why does everyone think good ping=good TCP/IP transfer? A ping uses ICMP
and if you favour the ICMP-packets, you get wonderful pings and that 
doesn't help you for any other TCP/IP packet!
The other thing is to give mldonkey very little priority...that will 
lead to better overall performance and to drop mldonkey-packets if they 
can't be sent...
You can't have both: good mldonkey DL AND good overall TCP/IP performance.
