Another workaround is blacklisting the 'rpcsec_gss_krb5' kernel module
(in /etc/modprobe.d/blacklist.conf) -
# Blacklist rpcsec_gss_krb5 kernel module; needed for quick NFSv4 mounts, ref. bug https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/1270445
blacklist rpcsec_gss_krb5
But obviously the NFS subsystem should not be attempting to load this at
all if the system isn't using Kerberos (i.e, no Kerberos keytabs or
krb5.conf files)

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.
