Total Number of tags in singel kepserver Instance

Hi,

What is the maximum number of tags that can be configured against a single kepserver instance in a Server without any performance issue? I know the number of channels and devices are depends on the driver used. but my question is not about it. It is all about total number of tags per single Kepserver Instance without any performance issue. Your answer will be highly appreciated.

Thanks.

Below are the system scenarios.

1) Only Kepserver is the application running in the server except other Windows OS service.

2) Using One device per single channel configuration.
