Abstract
With the rapid development of Internet technology, the software system in high-concurrency scenarios is facing increasingly severe performance challenges, and the traditional architecture design has been difficult to meet the needs of modern applications for response speed, stability and scalability. So this paper focuses on the software architecture design and performance optimization of high concurrency systems, aiming to propose an efficient, flexible and scalable architecture scheme to deal with complex and changeable practical application scenarios. By analyzing the advantages and disadvantages of the current mainstream architecture mode, combining the distributed computing theory and practical engineering experience, a hybrid architecture model based on micro-service and asynchronous processing is proposed, and the dynamic load balancing strategy and cache stratification mechanism are introduced to improve the system performance. The experimental part uses real business data for stress testing, and the results show that the architecture shows significant advantages in throughput, delay, and resource utilization. In addition, this paper innovatively proposes an adaptive flow control algorithm, which can dynamically adjust the system parameters according to the real-time load, so as to effectively avoid the overload phenomenon and improve the stability.
