Hi All,
I works with AM335x Starter Kit from TI, I modify the cpsw driver to works with
2 ports (cpsw0 and cpsw1).
Before this modification I have tested the performance on native driver with
this command.
on OBSD
nc -l 1234 > /dev/null
on host connected by switch 100Mbit/s full duplex (MAC OX 10.10)
nc 192.168.169.62 1234 < CentM
where CentM il file with 100MByte (created with makefile 100m CentM).
On BSD5.5 or 5.6 the time for this transfert is 93s = 8,6 Mbit/s
I have try the same transfert with Linux (on same board) the time is 9s =
89Mbit/s
The performance of transfert on OBSD is poor why ?
Driver ?
Kernel ?
Or mistake on my configuration.
I need ARM card with 2 ethernets (giga) Port to configure in routing from port
1 to port 2. I hope 200Mbit/s (linux performance) for this routing.
Thank for your help.
Bernard
