Hans Witvliet said the following on 08/26/2013 09:17 AM:
If you have just one mbox-file, sequential reading/searching mbox might
be fast, but when you mutate a lot, storing messages into individual
files and subfolders in separate dirs looks more efficient.

Quite true but there is a WTF reaction on my part.

WTF are you doing altering emails?

Or do you mean something different from that by "mutate"?

As for INCOMING! opening the mbox file and doing an append ... append
... append ... isn't inefficient. It probably more efficient that doing
a step and repeat of ''create, append, close'.

How much of a pizzing match do you want to engage in here?
Not least of all because different file systems grow files in different
ways and different file system handle growing directories on file create
in different ways. So mailbox vs maildir gets to be more like comparing
apples to picasso paintings than apples to oranges.

Hi Anton,

As Maildir puts everything in separate dirs/files, it seems to me that
it place a higher burden to the efficiency of the underlying filesystem.
Or is this a wrong assumption?

So it seems to me, when deleting one message (= one file) is less costly
then modifying an mbox containing 10,000 messages.

otoh, if only messages got added (like on a mailing list archive) adding
things at the end, and modifying the index is less costly than creating
separate files each time.

But ofcourse, i could completely mistaken regarding the innerworkings of
mboxes ;-)
