RE: big picture UDP/IP performance question re 2.6.18 -> 2.6.32

Sometimes I think it might be nice to run without
an OS at all :-)

We are looking at various kernel bypass approaches
for receiving packets and it's in my mind that
one of these may get us to running on newer
kernels without giving up performance.

If permissible in your environment, try running PACKET:tpacket_v3.

Also, I always wondered about the following in the output of:

net/ptype
dada          edsa_rcv+0x0/0x246
001b          dsa_rcv+0x0/0x225

and so when I'm fine tuning apps in virtual environments I nuke the
above during kernel compilation.
