摘要
为了提高Web系统数据访问的性能,对主要的缓存策略进行了研究,通过分析各种缓存的使用场景,针对Web系统的特点,提出了一种高性能本地数据缓存的实现机制。该机制同时支持对缓存的定期更新和请求驱动更新,能够根据待存储数据的特点,采用不同的缓存方式。实际测试表明,该机制缓存命中率高,可以有效减少平均响应时间,提高系统吞吐量。
In order to improve the performance of data access in Web system,this paper studied the main cache strategy and proposed a high-performance mechanism of local data cache. The mechanism implemented the timer driven cache and request driven cache,so the system could choose different cache according to the characteristics of the data to be stored. Actual test shows that,the mechanism increases cache hit ratio,reduces the average response time and improves the throughput of the system.
