Test purpose
Test the performance of EMQX Enterprise single node in a scenario of 100,000 concurrent connections and bridging 100,000 QoS 1, payload 1KB messages per second to RabbitMQ, and get the performance indicators, such as response time, CPU and memory usage.
Test config and tools
Test environment: VPC of Public Cloud Beijing 4 Test tool: XMeter Enterprise v3.2.0
Test machine configuration of EMQX and RabbitMQ
Conclusion
As shown in the above results, the EMQX on a 32C64G machine can support 100,000 concurrent connections and 100,000 messages with QoS 1 and payload of 1kB per second bridged and forwarded to RabbitMQ. During the traffic period, the CPU usage (user) stabilized at around 59%, and the average of CPU idle is 20%. Memory used stable, and the average response time for both connection and publish are in the hundreds of milliseconds.
