Today I had some time for testing AND physical access ... 

With bge0 bound to 100baseTX / full-duplex the transfer breaks down to
<100kBytes/sec, with 1000byseTX its about 250-350kBytes/sec, should be
~10MBytes/sec

ifconfig bge0 down
ifconfig bge0 media ... 
ifconfig bge0 up 

I will do some more and detailed testing next time I'm in our data
center, including the netstat-output etc.

Hmm. if_bge buggy? 
But, same machine on a FE-Switich worked perfectly (with 100MBit).

By default ifconfig says:

bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=1a<TXCSUM,VLAN_MTU,VLAN_HWTAGGING>

Any idea?
