Object Model Performance

As an estimation of performance, a Parent-Child Node system with 1,000,000 objects on child Node consumes the following resources:

Table 1. Test System Specifications
Component Host	CPU	RAM	Hard Disk
Parent Node	2.90 GHz, 8 vCPU	16GB	500GB
Child Node	2.90 GHz, 8 vCPU	16GB	500GB

Table 2. Actual Consumption
Component Host	CPU Usage (%)	RAM	Hard Disk
Parent Node	1%	2.7GB	SSD
Child Node	1%	4.1GB	SSD

This is a broad estimation of the performance characteristics created by the object model (no archiving or realtime changes) and should only be used for guidance, actual results are specific to the user’s system, network, use cases and other components installed.

Archive Performance

As an estimation of performance, a Parent-Child Node system has the capacity to archive 1,000,000 timeseries samples per second to a single data store, generated by the child Node.

Table 3. Test System Specifications
Component Host	CPU	RAM	Hard Disk
Parent Node	2.90 GHz, 8 vCPU	16GB	500GB
Child Node	2.90 GHz, 4 vCPU	8GB	500GB
MongoDB	2.90 GHz, 16 vCPU	64GB	500GB

Table 4. Actual Consumption
Component Host	CPU Usage (%)	RAM
Parent Node	10%	12.5GB
Child Node	2%	5GB
MongoDB	4%	31GB

This is a broad estimation of the performance limitations and should only be used for guidance, actual results are specific to the user’s system, network, use cases and other components installed. Memory consumption is largely defined by peak loads saturating the timeseries buffer maximum values setting. It is recommended to use faster disks for machines that host high throughput Nodes and MongoDB instances.

Realtime Performance

As an estimation of performance, the Node-to-Node communication has the capacity for 50,000-100,000 timeseries samples updating per second on the following standard hardware, on a low latency network environment (LAN, latency <50ms):

Table 5. Test System Specifications
Component Host	CPU	RAM	Hard Disk
Parent Node	2.90 GHz, 4 vCPU	32GB	500GB
Child Node	2.90 GHz, 4 vCPU	32GB	500GB

This is a broad estimation of the performance limitations and should only be used for guidance, actual results are specific to the user’s system, network, use cases and other components installed.
