Can anybody think of a quick workaround or fix for this, as it's clearly

The above is with a 4k client_limit, I'm definitely going to crank that up

If so and with no false data/state transmitted to the client it would be
not ideal, but not a critical problem either.

If you ne

Also an "iostat -x" oneshot summary and a few samples of when the machine

My current goal is to have 100k capable servers that work well, 200k in a

The later is a single-threaded process, so it will benefit from a faster
CPU core.
It can be dramatically improved by enabling process re-usage, see:
http://wiki.dovecot.org/PerformanceTuning
However that also means more memory usage.

There's another aspect of Ceph that may be of interest with Dovecot, using
the object storage interface.
However that's not supporting native Ceph interfaces and by its very
nature also is slowish, but has nice scalability.

How many concurrent connections do you (hello Timo) think dovecot in proxy
mode can handle? High performance mode of course in this case.
I'm interested in internal limitations, assume that CPU and RAM are
amply supplied.
Any and all feedback is appreciated.

Memory wise it's about 35% bigger than perdition and that's not subjective
at all. ^o^
About one MB per proxy process/connection for dovecot in my case.

If everybody can be taught to use only TLS (not IMAPS/POP3S) and all the
clients do support SNI, we can do away with the dedicated IP addresses.

ystems are plenty fast and any delay by having to (re)build the

But if you have a system with less reserves, users that access mail
very infrequently but get plenty of mail (so indexing at access time
will be an involved process) and no mass mail spikes, dovecot LDA
starts t

least with exim local delivery happens in a separate stage AFTER
