I use a P200 for a gateway but it's only got one eth card, so I can't 
really recreate your setup properly - I assume the SMB traffic is 
forwarded and not local traffic.

I can't even do 100Mbit when actually running anything on mine with a 
rtl8139 - I run out of CPU - doesn't seem to affect internet 
shaping/throughput.

I'll have a go at shaping on eth and see if I can recreate it when I 
have time.

When you say stalls, what happens eg just no throughput or dropped 
packets or just high latency - is swap being used etc.

Andy.
