I use chert as well.

I had 45 (or so). I wanted two searches for every mailing list. One
"tag:inbox and (...)" and the second only "...".

My current numbers (with hot cache) are bellow.
$ time notmuch count tag:notmuch
3243
0,00s user 0,00s system 72% cpu 0,011 total
$ time notmuch count to:notmuch at notmuchmail.org
2477
0,03s user 0,00s system 89% cpu 0,036 total
That is 36ms vs. 11ms. If these numbers are multiplied by 45 (or by 90
with the bug in notmuch hello), this makes the difference.
