typing slows down dramatically when typing digits in emails

[Eric S Fraga <e.fraga@ucl.ac.uk>]

Hello,

When composing an email in message mode in Emacs, completion works just
fine except when I type any digits (0-9) where there is an appreciable
lag.  Using the profiler, I get the following summary:

--8<---------------cut here---------------start------------->8---
        5482  82% - ...
        5311  79%  - completion--capf-wrapper

           4   0%                      + internal--syntax-propertize
           9   0%                    + dabbrev--make-friend-buffer-list
--8<---------------cut here---------------end--------------->8---

It comes down to dabbrev... maybe.

Is there any setting that I might have missed that would improve this?
I am supposedly using company mode, by the way, I think (at least, I
have company indicated in my mode line) and completion candidates only
popup after 5 keystrokes yet lag takes place as soon as I type a single
digit.

Thank you,
eric
