System Performance Guidelines
System performance is affected by many factors. When setting up your system, you should take into account:
For optimal system performance, we recommend that you:
- Use multi-core processors, with up to a maximum of 8 cores (for example, 2 x quad-core server processors). Adding more than 8 cores provides limited benefit.
- Choose the fastest possible memory bandwidth
- Split the ClearSCADA database across separate physical disks
- Use Solid State Disks (SSD) for storing historic and Event Journal data online (see Disk Drives and RAID Arrays).
NOTE:When using ViewX with HTTPS and certificates, attempting to run a script that connects to DBServer 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 ClearSCADA Guide to Scripting.
