I cannot help you with a comprehensive explanation, but at least I discovered similar timeouts while fiddling around with my new NFSv4+Kerberos setup. The first operation on a fresh mounted NFS share took ages (one minute is quite possible). I don't remember whether it timeouted or succeeded in the end. Now that everything is in place and working as expected, I no longer discover these timeouts. Every operation (read+write) to the NFS share, starting with the first one, finishs within milliseconds. > I tested it with sec=sys, and that shows no difference.

Not sure whether it is related, but apart from fixing Kerberos principal mapping and ticket cache handling, the missing PTR record for my Kerberos/NFS server was one of the last things I fixed.
