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 Redis, 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

Configuration of EMQX, Redis Standalone, and testers

Configuration of EMQX, Redis Standalone, and testers


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 Redis. All messages are written to the database in real time. During the traffic period, the CPU user stabilized at around 60%, and the average of CPU idle is 17%. Memory usage is stable. The average response time of connect and publish are at the level of millisecond.
