The arrival of high CPU core density, with commodity
quad-core notebooks and 32-core servers, combined
with 10gbps networking have transformed network
design principles for operating systems. This talk
will describe changes in the FreeBSD 6.x, 7.x, and
forthcoming 8.x network stacks required to exploit
multiple cores and serve 10gbps networks. The goal
of the session will be to introduce the audience
to general strategies used to improve performance,
their rationales, and their impact on applications
and users:
- Introduction to the SMPng Project and the follow-on Netperf Project
- Workloads and performance measurement
- Efficient primitives to support modern network stacks
- Multi-core and cache-aware network memory allocator
- Fine-grained network stack locking
- Load-balancing and contention-avoidance across multiple CPUs
- CPU affinity for network stack data structures
- TCP performance enhancements including TSO, LRO, and TOE
- Zero-copy Berkely Packet Filter (BPF) buffers
- Direct network stack dispatch from interrupt handlers
- Multiple input and output queues
Robert Watson is a researcher at the University of
Cambridge Computer Laboratory investinging operating
system and network security. Prior to joining the
Computer Laboratory to work on a PhD, he was Senior
Principal Scientist at McAfee Research, now SPARTA
ISSO, a leading security research and development
organization, directing government and commercial
research contracts for customers that include DARPA,
the US Navy, and Apple Computer. His research
interests include operating system security, network
stack structure and performance, and windowing
system structure. He is also a member of the FreeBSD
Core Team and president of the FreeBSD Foundation.
