Geo SCADA Expert System Performance Guidelines

System performance is affected by many factors. When setting up your Geo SCADA Expert system, you should take into account:

For optimal system performance, we recommend that you:

Choose the fastest possible memory bandwidth
Split the Geo SCADA Expert database across separate physical disks
Use Solid State Disks (SSD) for storing historic and Event Journal data online (see Disk Drives and RAID Arrays)
Ensure that log files are written to a suitable partition that contains sufficient disk space and does not impact on the space required for other files (see Move all New Log Files to a Different Location in the Geo SCADA Expert Guide to Server Administration).

For further guidelines, see the 'Geo SCADA Expert Performance Guidelines' document on the Geo SCADA Knowledge Base website (see https://community.se.com/t5/Geo-SCADA-Knowledge-Base/Technical-Guides/ba-p/278414).

When using ViewX with HTTPS and certificates, attempting to run a script that connects to the Geo SCADA Expert Server can cause long delays (of the order of 20 seconds) the first time you run the script after starting ViewX. This is because of the way that certificate revocation lists (CRLs) are downloaded from the Windows update server.

If you encounter this problem, we recommend that you contact your IT department.

For more about scripting, see the Geo SCADA Expert Guide to Scripting.

You can achieve high accuracy time (such as synchronizing time to within an accuracy of 1ms) using W32Time, providing that certain criteria are satisfied. For more information, see https://learn.microsoft.com/en-us/windows-server/networking/windows-time-service/support-boundary. However, if you choose to use another third-party NTP client to maintain accurate time, remember to disable Windows Time (W32Time).

Server class computers and virtual machines (VMs) on server class computers should not be used to run ViewX in a day-to-day operational environment; instead, appropriate client machines should be used. Client machines often have a higher graphics hardware specification than server class computers. This higher graphics specification is required to run ViewX in a day-to-day operational environment, within which users might perform graphics-intensive tasks such as viewing complex Mimics, or working with multiple or floating documents (see Client PC Specifications).

The standard graphics hardware on server class computers and on VMs on server class computers may only be adequate for running ViewX for administrative purposes (such as performing initial system configuration and user account setup).
