I also experience slow ethernet/internet connections with my mac mini, 1.5 ghz, 1gb ram and 64 mb vram. I setup a static IP address, no dhcp. I experience also slow LAN transfers, using Envoy3... Transfers just stop for say 10 secs and then it works again. Transfering data from a Pegasos2 to the macmini, via LAN, Ambient shows about 700 kb/s, doing the same from a Pegasos2 to another Pegasos2, Ambient shows 5.5 MB/s.
