摘　　要：高并发性能成为各种在线应用生存和竞争的关键因素。每个访问都需要涉及数据库高并发读取与写入,这会导致数据库性能下降,响应时间延长。为解决该问题,提出了一种高性能系统架构的设计方案。该架构采用多级缓存、热点探测、分布式锁、分布式事务等技术设计,能够有效地处理流量峰值。将该系统架构应用于电子资料平台中,通过系统性能测试发现,在不同请求数量的并发负载下,系统始终具有良好的稳定性和准确性,进而验证了该高性能系统架构方案的有效性。High concurrency performance has become a critical factor for the survival and competitiveness of various online applications.Each access involves high-concurrency read and write operations on database,leading to performance degradation and increased response times.To solve the problm a scheme for a high-performance system architecture is proposed.The architecture incorporates technologies such as multi-level caching,hotspot detection,distributed lock,and distributed transaction to effectively handle peak traffic.Applied on an electronic data platform,performance tests reveal that the system consistently exhibits good stability and accuracy under varying levels of concurrent loads.This validates the effectiveness of the proposed high-performance system architecture.
