I was talking about cheap switches (and that's pretty the same with 
adsl-routers). There is usually no way to configure (at the switch) 
which speed/duplex should be used and if you set your nic to a specific 
mode, the switch doesn't mention this. So it keeps on sending it's 
autosensepakets and waits for response. It get's timeouts and thats what 
  pulls down the networkperformance.
So you have to set your nic to autosense and you'll get a better 
performance, cause the nic responces to autosense.
