Hi,

i've little problem with net4801 and network speed. With iperf, max speed
is 30bmps.

PC1 (10.1.1.251) <-> eth1 (10.1.1.254) <-> eth0 (192.168.0.99) <-> PC2
(192.168.0.51)
network is 100Mbps full

iperf from PC1 client to PC2 server :

sudo iperf -c 192.168.0.51 -i 3
------------------------------------------------------------
Client connecting to 192.168.0.51, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------
[  3] local 10.1.1.251 port 56225 connected with 192.168.0.51 port 5001
[  3]  0.0- 3.0 sec  10.4 MBytes  29.0 Mbits/sec
[  3]  3.0- 6.0 sec  10.4 MBytes  29.0 Mbits/sec
[  3]  6.0- 9.0 sec  10.4 MBytes  29.0 Mbits/sec
[  3]  0.0-10.0 sec  34.6 MBytes  29.0 Mbits/sec

I've bering-uclinux 3.0.2 on CF with shorewall for routing

Is it possible to increase network speed because 30 Mbps is very small :(
Perhaps with sysctl ?

All feedbacks are welcome

Regards

Franck
