KEPware Server EX and usage of CPU

[AP_11774542]

Hi,
I'm writing to this support to understand if and how could be possible to reduce the usage of CPU when a big configuration of Kepware is running.

The configuration it is composed by almost 80 device configured to query each 10 seconds 2000 Modbus registers for each device, values are archived in a Microsoft SQL Server through Data Logger triggered each 10 seconds.

Actually only 2 devices ramps the CPU usage to 10-12% for the server_runtime.exe almost and I don't know what happen when I enable all the 80 devices, how can I reduce to the max the usage of CPU.

Which are the information that you need to support me in this issue?
Let me know and I can provide the screenshots or logs or config...

KEPServer EX V6.11.718.0
Modbus TCP/IP Ethernet V6.11.718.0
Data Logger PlugIn V6.11.718.0
