I also suffer from bad performance of notmuch new. I used notmuch some years ago and notmuch new always felt instantanious. Had to stop using it because internet was too slow to sync my mails :/ Now (with better internet and a completely new setup using mbsync) indexing one mail takes at least 10 seconds, sometimes even more. It can go into minutes when I get lots of mail (~30...). When I run it after a reboot I can have breakfast while notmuch starts up... This is all on spinning rust. I thought of getting an SSD but not in the near future. What I observe during that time: notmuch doesn't really need much CPU. iotop shows constant read and write with extremely low rates, under 1MB/sec. So I think it might be an issue in xapian? If there is anything I can do to help debug this please tell me Franz P.S.: @David: Sorry for writing only to you. GMail web interface only added you as recipient and not the list...
