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 Pulsar, 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 Pulsar

Test machine configuration of EMQX and Pulsar


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 Pulsar. During the traffic period, the CPU usage (user) ranges from 52% to 65%, with an average of 65%; and CPU idle ranges from 8% to 31%, with an average of 20%. Memory used stable, and the max didn’t exceed 23GB.
