Pushing the Limits of Kernel Networking
Session information has not yet been published for this event.
One Line Summary
This talk will cover the Linux kernel limits in terms of small packet networking performance, efforts to push those limits further, and tips and tricks to get the most out of the networking stack.
As network speeds continue to increase from 10Gb/s, to 40Gb/s, and very soon to 100Gb/s the rate at which packets can be transported increases putting pressure on the kernel to drive ever faster packet rates. This talk will cover what we currently know about the limits of the Linux kernel in terms of small packet networking performance, ongoing efforts to push those limits further, and a number of tips and tricks to get the most out of the kernel networking stack.
