Hi, Steve,

 Thanks for your reply.

 But I've already figured out that it is not a Fedora Core 1 NFS
problem, it is tg3 driver (for Broadcom gigabit) problem. The
problematic dirver uses more CPUs cycles, and offers only 60% speed
compared to the vendor's bcm5700 driver.

My former email has more details.

Thanks.

Are you seeing any rpc/tcp transmits? nfsstat will show rpc retrans and
netstat will show tcp retrans... Also any type of messages being logged
to /var/log/messages?
