Robert Watson's Slides from EuroBSDCon 2005

EuroBSDCon 2005 took place in Basel, Switzerland in November, 2005. Due to an injury, I was unable to attend the conference itself, and my talks were presented in absentia by Poul-Henning Kamp and Ed Maste, who have my greatest appreciation!

20051126-eurobsdcon2005-netperf.pdf - Introduction to Multithreading and Multiprocessing in the FreeBSD SMPng Network Stack (presentation)

The FreeBSD SMPng Project has spent the past five years redesigning and reimplementing SMP support for the FreeBSD operating system, moving from a Giant-locked kernel to a fine-grained locking implementation with greater kernel threading and parallelism. This paper introduces the FreeBSD SMPng Project, its architectural goals and implementation approach. It then explores the impact of SMPng on the FreeBSD network stack, including strategies for integrating SMP support into the network stack, locking approaches, optimizations, and challenges.
