One Line Summary

Discussing ongoing work to incorporate bulk transmit, lock removal, and other improvements for in-kernel packet performance.


In the networking Linux mailing list there has been recent work to support batch xmit routines out of the queuing disciplines and other devices. As well as support for running new queueing disciplines that require no locking.

Many of the kernel developers working in this area will be at LPC this year. This BoF provides a forum to discuss the latest improvements and proposals that have occured in previous conferences and on the mailing list. As well as share progress and results.
