存储缓存容量的测试方法

Test Method for Storing Cache Capacity

缓存对于存储的性能起着至关重要的影响。缓存大小以及缓存替换算法的正确设置,可以大幅度提高存储的性能,相反,对缓存不正确的设置则不能发挥硬件的潜能。本文根据缓存替换算法的特点,提出一种测试磁盘缓存容量的方法,并通过模拟实验验证了该方法的有效性。该方法具有通用性,可以适用于其他类型资源的缓存测量。

For the storage cache performance plays a crucial impact.Cache size and cache replacement algorithm is set correctly,can greatly improve storage performance,on the contrary,incorrect settings for the cache can not play hardware potential.This article replaces the cache according to the characteristics of the algorithm,we propose a method of testing the disk cache capacity,and through simulation experiments to verify the effectiveness of the method.This method is versatile,can be applied to other types of measurements cache resources.
