We found routing performance dropped significantly when configuring FreeBSD as a router, we are applying the following changes in order to resolve those issues and hopefully perform better. - don't prefetch the flags array, we usually don't need it - prefetch the next cache line of each of the software descriptor arrays as well as the first cache line of each of the next four packets' mbufs and clusters - reduce max copy size to 63 bytes - convert rx soft descriptors from array of structures to a structure of arrays - update copyrights Submitted by: Matt Macy <mmacy@nextbsd.org>
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The `buildkernel` and `installkernel` targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information. Note: If you want to build and install the kernel with the `buildkernel` and `installkernel` targets, you might need to build world before. More information is available in the handbook. The kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
