% Registration Networking Driver Performance and Measurement - e1000 A
% Case Study
% Proposal John A Ronciak (john.ronciak@intel.com)
Networking performance is a popular topic in Linux and
is becoming more critical for achieving good overall
system performance. This paper takes a look at what was
done in the e1000 driver to improve performance by (a)
increasing throughput and (b) reducing of CPU
utilization. A lot of work has gone into the e1000
Ethernet driver as well into the PRO/1000 Gigabit
Ethernet hardware in regard to both of these
performance attributes This paper covers the major
things that were done to both the driver and to the
hardware to improve many of the aspects of Ethernet
network performance. The paper covers performance
improvements due to the contribution from the Linux
community and from the Intel group responsible for both
the driver and hardware. The paper describes
optimizations to improve small packet performance for
applications like packet routers, VoIP, etc. and those
for standard and jumbo packets and how those
modifications differs from the small packet
optimizations. A discussion on the tools and utilities
used to measure performance and ideas for other tools
that could help to measure performance are presented.
Some of the ideas may require help from the community
for refinement and implementation.
