NFS Server Performance and Tuning Guide for Sun Hardware

Swap Space

Swap space is almost not needed because NFS servers do not run user processes.

To Set Up Swap Space
  1. Configure at least 64 Mbytes virtual memory, which is RAM plus swap space (see Table 4-3).

  2. Set up fifty percent of main memory as an emergency swap space to save a crash dump in case of a system panic.
