Hi,
I am wondering if Dovecot caches SQLite queries, and how well it works in high performance setups. I am particularly interested because in the below thread SQLite has been suggested as a means of Dovecot proxying connections to different ports. You can enable auth cache: http://wiki2.dovecot.org/Authentication/Caching
This is a per user caching though, it will still have to perform a sql look up each time a unique user authenticates to determine what port the proxy should forward each connection. Is that accurate? It caches the passdb lookup. The cache key consists of the given % variables in the SQL query. So if your SQL query doesn't contain %n/%u

Thanks Timo, I re-read the link you sent me, and it makes a lot more sense now. I will play around with the different variables (especially the port related ones), to get the desired result. Gah its late I should go to sleep!
