Test purpose

Test the performance of EMQX Enterprise single node in a scenario of 100,000 concurrent connections and saving 100,000 QoS 1, payload 200B messages per second to TimescaleDB, 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

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 200B per second persisted to TimescaleDB. All messages are written to the database in real time. During the traffic period, the CPU user ranges from 61% to 69%, with an average CPU user of 64%, and CPU idle ranges from 11% to 25%, with an average of 20%. Memory usage is stable. The average response time of connect during the test is at the level of millisecond, and the average response time of publish is 15ms.
