@onlybro thanks for the heads up on this. I think I understand the reason for that recommendation. But to understand this in the Cloudron context, once the box process starts up, we create a mysql connection pool. This is never destroyed and as long as the box process is up and running, the name resolving is only done during startup once. So I think we are good as is on this one.
I would actually be more curious about the memory settings you mentioned, that is probably more worthwhile understanding.
