This should be closed out. NFS clients moved to dynamic setting of the
tcp_slow_table_entries as evident of a default value of 2.

Title:
  Low default for tcp_slot_table_entries

Status in nfs-utils package in Ubuntu:
  New

Bug description:
  The value for /proc/sys/sunrpc/tcp_slot_table_entries seems unusually
  low on 12.04.1LTS.  The default seems to be 2:

  root at g:~# sysctl sunrpc.tcp_slot_table_entries
  sunrpc.tcp_slot_table_entries = 2
  root at g:~# sysctl sunrpc.udp_slot_table_entries
  sunrpc.udp_slot_table_entries = 16

  NFS documentation indicates that the default should be 16.  Early
  indications from my own testing is that increasing this shows an
  improvement in performance.
