about network interrupt

[Adrian Chadd]

Hi!

So em(4) doesn't use multiple CPUs on the traffic receive path, so
things won't scale all that well. can you retry with an igb(4) NIC?

I do have a TODO item to implement generic receive load balancing
based on a GSoC project and some of the RSS stuff that is in -HEAD now
but it's going to be some time before I can take advantage of it.

And I use one machine for test using different version of freebsd,then I find Freebsd 8 not using interrupt but 10 does!    In order to explain this I first guess it is the polling make it diff,but after I using "ifconfig em0 -polling" to disable polling of the network interface it does no effect! Now I can't explain it. Who can give me some advice?
