emacs slow with large threads

[Emilio Francesquini]

Hello there,

I recently ran into the same (slowness) problem when viewing long threads.
After some profiling I found out that disabling indentation did the trick
for me. In my case it went from unusable (>5 minutes) to ~3 seconds for
large threads.

(setq notmuch-show-indent-content nil)

Hope it helps.
