Hi,
  Unfortunately the situation has not really changed after the adding
of the computation of the checksums by the card.

I have done a new test with NFS (between a Knoppix 7.2 client and a Ubuntu 16.04 server).
The results are the same: 114Mbyte/sec for OpenBSD with firewall disabled (it
is enabled by default) and 70Mbytes/sec with NetBSD.

This is annoying while I don't understand what happens. I should still make some test
with a firewall to see how the transfer speed will decrease. With the slight
firewall (1 pass, two block rules) of OpenBSD, the speed was about 90Mbytes/sec.

By the way, is the default kernel from Netbsd SMP aware? 
Is a firewall enabled by default on NetBSD (like in OpenBSD)?

Would a current kernel be better?

Thanks for your help,

Best regards,

Alan
