I find Maildir inefficient in terms of perfomance - try doing a full text
search on a 12000 mails folder (as the one for this list in this machine).

Really?
I am on the brink on migrating from mbox towards Maildir because of
efficiency...

I was expecting the opposite from what you write....
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. Specially
when dealing with large (sub-)folders


Maildir, to my knowledge, is only more efficient when you do many inserts and deletes. And frankly, with good clients like Pine I don't even notice it.

Another alledged problem of mbox is concurrent ussage (like fetchmail adding an email, while the client does something else. In practice, I have never hit such a problem in 15 years.

With regards to btrfs, it uses a more efficient way of storing
meta-data, and does not need full 4K blocks for small files...

Well, reiserfs stored small files directly on the metadata tree, no allocation. I would like to read some document comparing both in this respect.
