A lot of the time if it goes even 2 minutes without a request, then the next request is a loading request which takes about 12 seconds to respond to and uses about 5 seconds of CPU time. Sometimes it does a loading request even when there was no traffic for only one minute. ...

Hello, Is there a way to use a real database(SQLite, Mysql, or even some non-relational one) as datastore for development, instead of memory/file datastore that is provided.
