With checksum offloading enabled on the ix(4) I got ~20% performance
improvement with relayd(8) using socket splicing. I think its worth to
enable this feature by default.
I also did my homework and tested all requested protocols:
IPv4 IPv6 4over6 6over4
ip/tcp check check
ip/udp check check
ip/icmp check check
ip/ip check check check check
ip/gre check check check check
ip/esp check check
ip/ospf check check
nfs v2 check -
nfs v3 check -
I used the following card for testing:
ix0 at pci3 dev 0 function 0 "Intel 82599" rev 0x01: msi, address
xx:xx:xx:xx:xx:xx
Looking for further testing or any OK?
Bye,
