Re: FreeBSD-6.1/amd64 bge(4) driver performance problems


Hm, interesting. I noticed that the auto-negotiation between the switch and the Broadcom NIC leaded to 100mbit, half-duplex. That's why i forced the Broadcom NIC to 100mbit, full-duplex.

I tried test scp(1) to a remote machine, using one of the BCM5721 NICs.
The average speed which has been reached was 200kBps.

Can you try forcing the interface back to 100mbit, half duplex? I've
seen issues with a switch before resulting in exactly that kind of
performance.
