Hi!
I am currently deploying Roundcube as the main webmailer for my university. So far my beta-tests with a select group of users have been very positive.
But before I push Roundcube on all my users who use webmail I wondered about the caching feature.
When do I use the index cache? And how do I cache? Inside my MySQL database or via a memcached instance?
My webmail service does not run on the same server as the IMAP service but on a different VM and in a different network but RTT between both is below 2ms.
The documentation mentions that caching may even reduce performance in some situations but does not specify which situations. So far I have not be able to experience any slowdowns or speedups while using the index cache so I don't know if I gain anything by using or not-using it.
Can anyone share any experience with the cache feature to help me decide.
Grüße, Sven.
