splitting this discussion into it's own thread from "MM3 occasionally chokes (?)".
Re-iterating background info for posterity:
we have been experiencing increasingly long boot ups from mailman-core over the past year to the point where it's at about 45min for the sequence to complete. We run couple of mailing lists (20+) that are anywhere between 100 and 10K+ members and most of them are low traffic.
From what I can tell all that time is spent doing some sort of indexing operations, I'm writing from memory since I can't restart the system to confirm that.
sizes of directories that containers use: 3.6G core 352M database 285M web
state of my queues (as far as I understand how to evaluate them:
$ for q in core/var/queue/*; do echo ${q}; ls ${q}/ | wc -l ; done core/var/queue/archive 1 core/var/queue/bad 3845 core/var/queue/bounces 0 core/var/queue/command 0 core/var/queue/digest 0 core/var/queue/in 0 core/var/queue/nntp 0 core/var/queue/out 7 core/var/queue/pipeline 0 core/var/queue/retry 1 core/var/queue/shunt 958 core/var/queue/virgin 0
what kind of tuning should we be looking into to speed up our boot-ups?
