Hello, I have a Licensed Ignition Module and there are about 5 projects running in Ignition. It gateway is connected to 10 DB instance at present. I get a frequent Database communication fault the maximum Queries per sec is 78 Quires/Sec. I would like to know if there is any limitation to the number of database connection with ignition or how can I optimize the Query rate. Any suggestion on this would be helpful.

Thank you.

There are no limits. 78 queries per second is a moderate load. I’ve seen systems with much more. You almost certainly are experiencing performance limitations in the database, not Ignition. No way to tell without more information about your setup.

Hi, I’m using SQL EXPRESS 2014 hosted on a Windows Server 2012 R2 with 32GB RAM/4TB Memory, any ideal server architecture that you would suggest for running multiple ignition projects with minimum 1000 tags?
