Since MAXPHYS now allows the FreeBSD NFS client to do 1Mbyte I/O operations, add a sysctl called vfs.nfsd.srvmaxio so that the maximum NFS server I/O size can be set up to 1Mbyte. The Linux NFS client can also do 1Mbyte I/O operations. The default of 128Kbytes for the maximum I/O size has not been changed for two reasons: - kern.ipc.maxsockbuf must be increased to support 1Mbyte I/O - The limited benchmarking I can do actually shows a drop in I/O rate when the I/O size is above 256Kbytes. However, daveb@spectralogic.com reports seeing an increase in I/O rate for the 1Mbyte I/O size vs 128Kbytes using a Linux client.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
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), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
