[Bug 1098211] Re: Low default for tcp_slot_table_entries

[Michael Gutteridge]

I concur- though I haven't yet found anything but second-hand reports that this is the case (i.e. table entries are dynamic and with the upper bound controlled by sunrpc.tcp_max_slot_table_entries).

I'm uncertain of the best way to close the issue... set state to
"invalid"?

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.
