>Description:
Using a via-rhine based network card, there is a big performance problem
with MONO-THREAD file transferts using SCP, FTP or HTTP.

When I make a file transfert between two boxes (My Box and a Debian box)
plugged in the same LAN : 

Debian => My BSD BOX : Between 5 and 7 MB/s
My BSD BOX => Debian : Between 200 kB/s and 1 MB/s

There is no traffic shaping between these two boxes but there is an IP router.

Another test done : The same boxes (Debian and BSD) plugged on a high speed
LAN and my ADSL 1 MB/s connexion at home.

Debian => ADSL : 1 MB/s
My BSD BOX => ADSL : 200 KB/s

Could it be a bug with the via rhine driver ?

Regards,
Olivier BONHOMME


>How-To-Repeat:
Just make a file transfer between two boxes.

 Olivier,
 
 I'm sorry nobody took care recently about your PR.
 
 Do you still see the low throughput situations with a more recent
 FreeBSD release (say 6.3/7.0)? I think the network subsystem has
 undergone a lot of improvements and performance has been one of them.
 
 Thanks!
