You have been subscribed to a public bug:

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.

** Affects: nfs-utils (Ubuntu)
