I vaguely recall an issue similar to this one, which also arose after an upgrade
to one of my machines. It turned out that I needed to be running portmap on the
*client* machine also, and once this was done mount calls happened as fast as
they had before.

So, to summarise, if A is mounting an NFS filesystem from B, try enabling the
full suite of portmap/nfs* services on A also, and see if that solves the
problem. Then switch off specific services until the problem re-occurs, and
you should be left with the only services you need.
