NFS: id mapping slowness due to DNS issues

Solution Verified - Updated -

Issue

Approximately every 10 minutes, commands that require NFSv4 id mapping (string user@domain to local system uid/gid translation) take long to respond i.e. a ls -l on NFSv4 mountpoint can take 20-30 seconds to complete. Subsequent run goes fast.
