[* I have disabled the DMA, because otherwise the boot process is halted
and trying to reset the hard disc, because of a strange timeout]
----------
I used to experiment with two network cards simultaneous connected to
the same switch and using netgraph, but when I was using the local
100Mbits net, the load of the server went > 6 [because in netgraph, one
card is working on promiscuous mode...]. So I am using only wb0, with an
average load of the machine of 0.12
Finally if I put the value
net.inet.tcp.delayed_ack=0
Then comparing with the previous situation the speed is much worst. That
is
the value net.inet.tcp.delayed_ack=1 is much better (on my local
100Mbits net). This was measured for both small and large files (7MB,
and 700MB). All the tests are done using Windows XP. On my smb.conf I
only have TCP_NODELAY in socket options.
P.s. I disabled the NFS server [because this is an nfs server as well
for other machines] and the samba read/write speed on my 100Mbits
network has increased to 3 Mbytes/sec (no load on the machine). This is
still lower than the 7Mbytes/sec on the local 100Mbits network that I
have using FTP.
