NFS V2 Performance

• high overhead

  • primitive operations
  • paths dissected by the client
  • reading /foo/bar/baz:
    • “lookup foo”
    • “lookup bar”
    • “lookup baz”
    • “read from baz”

• no client side caching defined by protocol

  • clients typically cache for O(1s), no validation

• all operations defined to be synchronous

  • some servers did asynchronous writes all the same
