Server Processor Usage

XRatel Perfmon OPC/DDE Server - Server Memory Usage

Memory usage was monitored on every second and the average memory use was 11MB.

Server Memory Usage

XRatel Perfmon OPC/DDE Server - Server Network Usage

Network usage was monitored on every second and the average network use was 6% for data in both directions.

These values were calculated based on a 100Mbps ethernet link.

Server Network Usage

XRatel PerfMon Tools server successfully monitored 310 items every second with low resource usage. This situation can be easily reproduced by tuning the server profile and scanning only useful items.
