中文摘要: 为了解决大型遗留系统日益凸显的性能与安全问题，保证系统的可靠平稳运行，分析和研究了遗留系统的性能及安全现状，并在此基础上提出了优化策略.分别从前端、数据库、服务器、系统架构、系统安全五个方面阐述了优化方案，最后结合实例进行了优化策略验证.验证结果表明，该方案可以有效提升遗留系统的性能和安全等级.
Abstract:In order to solve the increasingly prominent performance and safety problems of large-scale legacy systems, and to ensure the reliable and stable operation of the system, the performance and safety status of legacy systems are analyzed and studied, and an optimization strategy is proposed based on this. The optimization scheme is described from five aspects: front-end, database, server, system architecture, and system security. Finally, the optimization strategy is verified with examples. The verification results show that the scheme can effectively improve the performance and security level of the legacy system.
