NFS, Sun's distributed computing environment, runs as kernel threads and uses the kernel scheduling class SYS. Since scheduling allocation for NFS is not managed by the Solaris Resource Manager SHR class, no CPU resource control of NFS is possible. The Solaris Resource Manager product's ability to allocate processor resources may be reduced on systems offering extensive NFS service.
NFS can, however, be controlled by using network port resource management. For example, Solaris Bandwidth Manager can be used to control the number of NFS packets on the server. NFS can also be managed in some cases by using processor sets to limit the number of CPUs available in the system class.
