This line here:
rw,relatime,vers=3,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.0.6.9,mountvers=3,mountport=35079,mountproto=udp,fsc,local_lock=none,addr=10.0.6.9
is handled by autofs which is configured through (FreeIPA).
I could increase the wsize and rsize though but not sure what value to
define.
