63 I used to use spinning rust and also noticed things were slow. This
\r
64 is in fact mostly not xapian - but rather crawling the Maildir. I
\r
65 improved this early on in notmuch history by reducing the number of
\r
66 seeks needed when traversing the Maildir hierarchy (e.g. stat in
\r
67 i-node order, which is roughly on-disk order).
\r
69 I'm about at the point where I'm going to take my git mail store
\r
70 experiments and get them really to work (and everyone will have to use
\r
71 'notmuch cat' or the like to access the messages) which should provide
\r
72 both great storage efficiency, much faster backups of your Maildir as
\r
73 well as having way fewer paths to traverse checking for new mail.
