If you are a big shop like Google you are always looking to squeeze all the performance juice you can out of your CPUs. Given the large number of machines deployed, a 1% performance improvement could mean millions of $$ in savings in both capital and operational costs.
In this talk, monsieur Eric Dumazet - the man sometimes refered to in passing as some form of ninja - will describe changes introduced by Google that help double TCP receiver efficiency in their datacentres.
Eric will discuss various issues that had to be overcome and a variety of tuning that was needed to achieve these performance improvements.
