Small size reference system
The small size reference system is constructed with 5000 Tags of data type double. Tags are getting live data from OPC UA data source with 2 second collection cycle creating total data ingestion load 2500 values/second. Data is stored in StreamHistory with default compression settings, and there is one aggregate (AVG) collected for each Variable. Additional data ingestion load is created by collecting 3 OPC events/s with standard attributes.
Small system reference configuration.
Small reference system | |
|---|---|
CPU | 4 Core (Broadcom BCM2837B0 quad-core A54 (ARMv8 running in ARMv7 32-bit compatibility mode), 1.4 GHz |
