7.1-PRERELEASE : bad network performance (nfe0)

I've serious network performance problems on a HP Turion X2
based brand new notebook; I only used a 7-1Beta CD and
7-STABLE on this thing.

Scp-ing ports.tgz from a rock-stable 7-STABLE server to it gives :

  # scp -p ports.tgz login at mv:/tmp/
    ports.tgz                             100%   98MB  88.7KB/s   18:49 

(doing the same thing by copy from an nfs-mounted disk even
 takes mores than an hour ...)

Doing a top(1) aside, just shows the box 100% idle :

   12 root     171 ki31     0K    16K CPU0   0  38:55 100.00% idle: cpu0

   30 root     -68    -     0K    16K -      0   0:00  0.00% fw0_taskq

I tested :

  Update Bios

All don't seem to matter to the problem.

I put two tcpdumps (server and client during another scp(1) ) on 

I'm far from an expert on TCP/IP, but wireshark "expert info" shows
lots of sequences like :

  TCP Previous segment lost
  TCP Duplicate ACK 1
  TCP Window update
  TCP Duplicate ACK 2
  TCP Duplicate ACK 3
  TCP Duplicate ACK 4
  TCP Duplicate ACK 5
  TCP Fast retransmission (suspected)
  TCP ...
  TCP Out-of-Order segment
  TCP ...

As usual, feel free to contact me for further info/tests.

Thanx, Arno
