+\r
+The speed comparisons between vanilla notmuch_addresses.py and\r
+nottoomuch-addresses.sh are going to be flawed in that they do different\r
+things. It's comparing apples and oranges.\r
+\r
+notmuch_addresses.py looks for matches in the recipients of mails the\r
+user has sent. Nothing else. notmuch_addresses.py filters out multiple\r
+names for one email address using a popularity contest.\r
+\r
+AFAICT nottoomuch-addresses.sh scans all the addresses in all the\r
+mails. It has no logic for filtering out multiple names for one email\r
+address, and just returns all matches.\r
+\r
+Personally I would like to have best of both worlds, and I'm using a\r
+modified notmuch_addresses.py that matches all the mails I have, and\r
+cleans up the duplicate results. Unfortunately that does have a toll on\r
+performance, taking about a second on my system for typical searches,\r
+cache hot, while nottoomuch-addresses.sh takes less than a tenth of a\r
+second. It is enough to be annoying, I'm afraid. Even so, it's not a\r
+fair comparison because notmuch_addresses.py wasn't designed with this\r
+in mind, and nottoomuch-addresses.sh maintains its own database and does\r
+less.\r
+\r
+One just needs to pick the tool that fits the needs best.\r
