Nacos service discovery performance test report

Test purposes

Main understanding Nacos service discovery performance load and capacity, to help us better manage Nacos performance quality, help users use of assessment Nacos system load faster.

Testing tools

We use the research of PAS performance evaluation service platform for pressure measurement, the principle is based on the use of JMeter engine, the use of PAS to automatically generate the JMeter scripts, intelligent pressure measurement.

Test scenarios

The following test scenarios are service discovery interface:

Verify Nacos service discovery that the ability to register instance
Verify Nacos service discovery that the ability to query instance
Verify Nacos service discovery that the ability to delete instance

Test data

1. register instance

Nacos service discovery registry instance the performance of the interface, call the HTTP interface test. The measured 3 nodes cluster performance under different pressure:

machine*concurrency num	service num	register instance num	TPS	RT(ms)	MIN RT(ms)	MAX RT(ms)
1*100	80301	84965	1793.41	54.63	0.8	1200.86
3*50	529321	819226	12574.8	15.8	0.45	3499.59
4*50	609726	836870	13000	18.54	0.46	3038.48
4*100	777262	927169	13257	35.65	0.48	3231.2

2. query instance

Nacos service discovery query instance of the performance of the interface, call the HTTP interface test. The measured 3 nodes cluster performance under different pressure:

machine*concurrency num	service num	register instance num	TPS	RT(ms)	MIN RT(ms)	MAX RT(ms)
1*100	80301	84965	3092.16	30.86	0.81	509.4
3*50	529321	819226	12574.8	15.8	0.45	3499.59
4*50	609726	836870	15603	16.41	0.42	3042.17
4*100	777262	927169	13604	34.19	0.43	3434.1

3. delete instance

Nacos service discovery delete instance is given to the performance of the interface, call the HTTP interface test. The measured 3 nodes cluster performance under different pressure:

machine*concurrency num	service num	register instance num	TPS	RT(ms)	MIN RT(ms)	MAX RT(ms)
1*100	80301	84965	1118.95	14.08	0.7	597.43
3*50	529321	819226	14508.53	11.23	0.4	3274.49
4*50	609726	836870	15476.93	16.02	0.38	3106.23
4*100	777262	927169	11940.9	40.33	0.42	51052.46

Test results

Nacos service discovery performance test is aimed at a key function, through the pressure test was carried out on the 3 nodes cluster, can see the interface performance load and capacity.

Service for up to 60w pressure measuring capacity, instance registered number up to 110w, cluster running steadily, the desired;(note: due to the registered instance using the HTTP interface, did not report to the heart of the TPS is included, if you want to support millions of instances of heartbeat report, need expansion and cluster level, and tuning tomcat and kernel parameters)
Register the TPS/query instance above 13000, interface to achieve expected;

The tests only temporary instance/query/cancellation of registration, no persistent instance (subsequent);

This test provides you as reference, if there are any deficiency or deviation, please correct me! If you have any other requirements on the performance, can you give us the issue.
