Heya,

I have an AMD Alchemy Db1100 evaluation board,
which has the Au1100 MIPS cpu (using NetBSD-evbmips).
It Runs -current off of an 'mdsetimage'd kernel.

My setup is as follow:

[client] -> [VLan Switch] -> [Au1100] -> [Internet]

I am using the Switch to tag the Ethernet frames coming in 
from the client as vlan #4. The Db1100 board has only one Ethernet
interface, so I created a vlan4 interface, which is receiving the 
tagged frames, and then ipnat translates everything out of aumac0,
which is the original interface. It all works very well, except for 
one major thing: performance. Performance is somewhere along the lines
of 1.5Mb/s, which is a little wierd, since the same setup on my
pIII laptop running netbsd yields around 70Mb/s.

Am I wrong here, or is the processor simply unable to deliver 
higher throughput?

Thank you,
