FS-LRU: A page cache algorithm for eliminating fsync write on mobile devices

摘要

In mobile environments, frequent fsync system calls negatively impact both performance and endurance of NAND-based storage. In this paper, we propose a novel page cache algorithm, called FS-LRU, that reduces the negative effect of fsync call by using hybrid DRAM and NVRAM memory architecture. Our experimental results show that FS-LRU outperforms the traditional LRU by up to 39.5%.
