Recorder - # of DB queries to expect?

While trying to debug frequent recorder database connection losses I checked the database (external MySQL DB) and realized that there is permanently a high number of queries happening - for my installation it is around 15K-25K queries/second.Is this a reasonable # to expect ? I understand that this # is very installation/configuration dependend …

I already do exclude high frequency items in the configuration, can probable prune it down even further - but before that I do want to understand what to expect here.

Sorry if this is the wrong pace to ask such kind of question but couldn’t find a better place to post this.

Analyze the queries, maybe you will find out “whats happening”
