[Bug 1270445] Re: slow NFS4 without "NEED_GSSD=yes"

[Anders Hall]

Can confirm speed-up with blacklisting rpcsec_gss_krb5 on the client
side. rmmod also works as a temporary solution.

I also tested the options to turn of security completely on the nfs-
server and nfs-client, which is well documented despite numerous
variables in man pages. However, those settings appears to confuse the
communication between the client (e.g., sec=none,incesure,NEED_GSSD=no,
etc) since it still uses rpcsec_gss_krb5. sec=none on the server side
seems useless in the same fashion.

Title:
  slow NFS4 without "NEED_GSSD=yes"

Status in “nfs-utils” package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 14.04 NFS4 client has slow access to NFS - share, if standard
  in /etc/default/nfs-common is left as "NEED_GSSD=".

  In syslog message 
  [406568.806179] RPC: AUTH_GSS upcall timed out.  
  [406568.806179] Please check user daemon is running.
  can be found.

  If default is changed to "NEED_GSSD=yes" access speeds up to normal (= good as in 12.04).
  I do not use Kerberos, so to set this option to "yes" does not make sense.
