At first, thanks a lot for your responses. According to infos I found
in the list archive I changed the values for net.inet.ip.ifq.* as follows
net.inet.ip.ifq.maxlen=1024 (256 * number nics)
net.inet.ip.ifq.drops=0
net.inet.ip.ifq.len=0
This had no effect on the network throughput.
In the next step I increased the value for net.inet.tcp.recvspace and
net.inet.tcp.sendspace to 262144 and that had big impact on the
network throughput.
The network throughput increased from 550Mbit/s to 940Mbit/s.
Because of this effect I would like to know if there is detailed
documentation availbale, describing the sysctl values and there
effects? Unfortunately the manpages don't describe these things detailed.
sysctl(3) is one way you could go, I found it quite helpful . Also you
could search the list for aditional info. henning@ explained the impact
of net.inet.ip.ifq.maxlen in of his mails to the list.
Best regards,
