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.
