Are the nfsd versions that you're setting being respected? You can
check with "rpcinfo -s" or "cat /proc/fs/nfsd/versions".
You can change the number of threads on the fly with "echo 1 >
/proc/fs/nfsd/threads".
I don't use systemd on Gentoo but for the nfs-utils upstream-shipped
systemd units that I think that Gentoo's using, you have to re-run
nfs-config.service - or run the script that it calls - in order to
update the "/run/sysconfig/nfs-utils" environment file that's sourced
by the nfs-server.service unit.
Does "/var/lib/nfs/v4recovery/" exist?
Does adding the client to "/etc/hosts" - or to your reverse dns zone -
eliminate the delay?
