Hi

Sorry this will be a big list of questions but they might help narrow
down the problem. 

How long does 

notmuch show --format=json thread:thread-id  > /dev/null

take? Is it much faster after the first run? What about the same with
the added cli option --body=false?

(you probably want something like  echo 3 > /proc/sys/vm/drop_caches
between batches of runs)

Do the messages have html parts?

Also what disk are you using (and does it have any other significant
activity happening)? And what version of notmuch are you using?

Best wishes

Mark
