[olug] Good Stuff - Google contributing to linux kernel

I found it interesting, thought I'd pass it along
Receive packet steering -
except: Contemporary networking hardware can move a lot of packets, to the
point that the host computer can have a hard time keeping up. In recent
years, CPU speeds have stopped increasing, but the number of CPU cores is
growing. The implication is clear: if the networking stack is to be able to
keep up with the hardware, smarter processing (such as generic receive
offload <http://lwn.net/Articles/358910/>) will not be enough; the system
must also be able to distribute the work across multiple processors. Tom
Herbert's receive packet steering <http://lwn.net/Articles/361440/> (RPS)
patch aims to help make that happen.
