摘　　要：中国科学院仪器设备共享管理2.0系统(简称IBBS@CAS)是一个用于仪器预约和管理的应用系统,它提升了设备利用率、降低了仪器的操作成本,实现了工程性的创新.运行6年多以来,它为用户提供了良好的功能性服务,但其性能却远远没有达到要求.为了发现系统性能瓶颈,对仿真系统进行性能测试和日志分析.通过实验分析,提出解决方案.在仿真环境下系统性能得到了很好的优化.实验数据表明,在特定场景下系统响应提升35%左右.Instrument Booking and Billing System （IBBS@ CAS） is a web application for instrument of Chinese Academy of Sciences Version 2.0 reservations and management, and it increases facility utilization, reduces operating cost and realizes engineering innovation. During about six years running, it provides an exceptional functional service, but its performance needs are not reached yet. In this study, under the condition of system limits, we carry out experiments on simulation environment to find out performance bottleneck by performance testing and log analysis. Then we propose a solution to enhance the IBBS@ CAS. The solution ensures that the performance of system improves to meet user requirements in simulation environment. The experimental results show that the system response time is reduced by about thirty-five percents in a specific scenario.
