BTW: This post is a followup to my "2.3.7 slower than 2.3.6?" post from back in July.
Fixed by https://github.com/dovecot/core/commit/5e9e09a041b318025fd52db2df25052b60d0f... and will be in the soon-to-be-released v2.3.8.
I stopped 2.3.7, copied over the index files from the ramdisk into the physical "realm" and restarted with a fresh 2.3.8. It probably takes a few days to be absolutely sure.
So, in general the performance issues are gone.
But...
I'm seeing odd hourly spikes almost every hour, on the hour. You might say: Well yes, that's a cronjob sending lots of mails. But it isn't. There's not more or less mail coming in at that very moment.
I suspect something in dovecot running every hour (DH key regeneration?)

2.3.7 does not generate DH keys. It's been removed since 2.3.0
Is it possible for you to track and find out which process is causing the peak?
