摘　　要：随着网络的发展,越来越多的用户开始考虑构建服务器,但磁盘性能不高一直是其所面临的问题。磁盘的性能与缓存速度有着密切的关联。在原有的Cache算法中引入数据压缩算法,并采用线程机制并行调度处理数据,以减少磁盘读写的I/O次数,可以提高磁盘数据读写性能,带来更高速有效的数据处理能力。With the development of website technology, more and more consumers begin to construct their own services, but they are always worried about the low performance of their disks. The feature of disks has a close relation with the cache speed. The article describes how to reduce reading or writing times on disk I/O and improve disk data-processing performance by reinforcing the reading and writing of disks. The data-compression algorithm is embedded into the cache and the thread parallel principle is adopted efficiently, resulting in faster data processing speed.
