When I was trying to reproduce this behaviour. I realize I have an
snippet that just loads when I start emacs as server-process.
--8<---------------cut here---------------start------------->8---
(eval-after-load "ol-bbdb" ;;; it's part of org
  '(progn
     (add-to-list 'org-bbdb-anniversary-format-alist '("custom" .
                                                       (lambda (name years suffix)
                                                         (concat "[[bbdb:" name "][" name "'s "
                                                                 (format "%s" years)
                                                                 suffix " custom anniversary]]"))))))
--8<---------------cut here---------------end--------------->8---

So. That was the reason I saw a different behaviour when launching emacs
as nw and when launching emacs-as-process. Conclusion. Sorry for the
noise. We just need to focus on 'satisfactory performance'.
