I find Maildir inefficient. :-p

+1 for the appropriate definition of 'efficient'.

Actually I think that's wide enough. Maildir consumes inodes and I've always
found that its difficult to get a good balance of inodes to data with the
ext? family of file systems. Rather than waste time doing admin work
fiddling and rebalancing (If I wanted to be an IBM/CICIS system administrator
I wouldn't have chose UNIX) I use ReiserFS and BtrFS. They work, are robust,
don't need fiddling with for journalling and crash recovery - the "just
work". Every time I use ext? I get hassle with inodes vs data. Maildir
rather that mbox will just aggravate that.

Right.

I keep a largish local nntp storage (from opensuse nntp forum) with
leafnode, stored on a reiserfs partition, and it takes a huge time to do a
local text search. Millions of files to look at.

I don't know about NNTP, but email is usually indexed, at least by date, most likely subject and sender and possibly by mail-ID. Dovecot also has the option of using something like Plucine for full text indexing for the body.

IIR NNTP headers aren't that different from email headers; perhaps dovecot could be persuaded to manage and index those files :-)

Btrfs? I don't know how it compares to reiserfs in terms of small files.

Target is 'same or better'. I have no complaints about performance; I just wish the fsck on boot actually did something :-/

Dovecot is another one of those wonderful programs that once you set it up
'just works'.

Yep. Well, I have to do some adjustements for the new version, though.

Sadly 2.x is radically different from 1.x in many ways. :-(

But what struck me was how that site admin _boasted_ of how he had to be
there tuning and tweaking as the load profile & demand changed though the
day, and more. Fun for Geeks, yes, but when I look at the overall trends in
business its about getting things done. Part of the selling point of tablets
and smartphones and some of the pre-Balmer versions of Windows was that they
"just work".

Indeed fun, but not for a job: it becomes routine and boring. Computers
should be better than people at routines.

And 'smart' enough to 'tune' themselves.

I realise that there are many people out there who enjoy fiddling with the
guts of systems; I do too. But that isn't the way production systems in
business should be run. They should 'just work' and keep working. They need
to be stable and predictable. No surprises. No need to fiddle and tune and
optimise.

Absolutely!

A mind is a terrible thing to waste when a computer could be programmed to do that boring, fiddly jobs so much better. Computers don't get distracted, don't turn of for work late with a hangover, don't have BOFH mentality (no, really). As Norbert Weiner said "Render unto the computer the things that are the computer's and unto man the things that are mans'". Doing the computer's job is no job for humans.
