Existing systems are generally based on traditional single-application architectures. With the continuous improvement of user requirements and the continuous improvement of website functions, there are shortcomings such as monotonous application function module obfuscation, low deployment efficiency, difficulty in extension functions, and high cost of technology and iterative methods. Therefore, the microservices technology gets attentions and adopted in project development. The microservices architecture has the advantages of easy development and maintenance, partial modification and deployment, easy extension functions, and unlimited technical options. In this work, the advantages of microservices application was studied, and setup an B/S system for performance testing. An experimental scheme for thread response time, throughput, and deployment time was designed and tested using Jmeter testing tools. The test data of 20 and 50 concurrent users were analyzed. Experimental results show that microservices has greater performance advantages and higher efficiency.
