The while the Zorro2 variant can transfer 3.5mb/s at most the Zorro3-variant has a signifficantly faster LAN<->Amiga interface of 6-7mb/sec. However, the SANAII-IP Stack is not very efficient and eats much of the performance, thus 1-2MB/sec are the maximum observed right now. +At present there are two firmwares: One for Zorro2, which runs in every Amiga with Zorro-Sots and one for A3000/4000, which puts the LAN-Chip into a Zorro3 environment.
