Poor Performance Data Refresh

[sinced]

I am facing some performance issues with the data actualization on a process display screen. There are many tags on the process displays and sometimes it can take up to 12 second to get data refreshed and correctly displayed.

Aveva Plant Scada Version: 2023 R2

Server Operating System: Windows 11

Server SSD: 500GB

Server RAM: 16GB

Server Processor: 12th Gen Intel Core i5-12500T (12 CPUs), 2Ghz.

The same hardware configuration is applicable for the unique client machine.

Hi @sinced 

I'd recommend reaching out to AVEVA or Schneider technical support to troubleshoot this issue.

Things I'd be looking at if I were trying to debug this system:

- Take a look at syslog.dat and IOServer_Syslog.dat for any indication of interruptions

- Look at machine resources (is memory or CPU high, any specific processes consuming a lot of CPU?)

- Is antivirus running, has it been configured to exclude Plant SCADA data directories?

- What protocol or drivers are being used in the project? Any bottlenecks or timeouts? Any devices offline?

Wish you all the best.

Kind regards

Olivier
