no it wasnt.
recources consumption raises super proportional, starting from player number 2.
however, since the server dont take much cpu resources, its all ok. the full tdm would take 30% of 1 core @ 1,8Ghz. Network traffic is ~3-5 Mbis/s then.
so everything is pretty idle on that side.
u need a strong client in order to play this (or a smaller resolution)
its the sad fact, its just a test btw...
