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.
