Why did no-one tell me? Why wasn't it mentioned?
nfs_do_symlink_cache is set to 1 by default, and boot-and-login yields
about 3 readlink operations as reported by nfsstat -c. Set it to 0 (or
use 2.3) and it takes about 70 here (we use amd, which means that a lot
of readlinks are local to the machine, but are readlinks none the less).
Symlinks have gone back to the server since NFS has been around, and at
last it's been fixed!
