Thanks for the suggestions.
Here’s the output of perf in a `bash -x` session.
(From what I can tell, the bulk of the output from the -x flag
is for two plugins I use, direnv and tmux-git.
FWIW, these are both also installed on my laptop, where pass runs way faster.)
$ perf stat -d pass ls
+ perf stat -d pass ls
