>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

Just make a file transfert between two boxes.
