It means your database is broken or simply not fast enough. Share more details about your setup. ---

Share the details about your database, because that is what is broken. - What DB brand and version? - Where is the DB located? (Same machine? Same LAN? Nearby data center? Far away data center?) - What query rate is the DB connection status page showing? (Screenshot that.) ---

MicrosoftSQLserver its on same Lan and here is a screenshot of the queryrate ![Capture](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/2/c2d7782344e694ac5999734115e2a658b5653358.png) ---

Show the status details page for that S&F engine. That will show the corresponding data delivery rate. (I suspect your DB is simply not powerful enough for the number of tags you are trying to historize.) ---

Your connections are almost completely saturated. Pretty much aligns with what @pturmel is saying about the database not being powerful enough. Is the server that the database is on showing any issues? ---

Is this server a VM or a Physical Server? How much RAM is available on the server? Are there any other applications running on the same server as the SQL server, or is it a standalone server?
