Abstract
AimingattheproblemofslowmountspeedofYaffsfilesystemoccurredwhentobeappliedinstoragedeviceswithlarge capacity,we propose a new improved method,and implement it in Yaffs2 file system.By adding appropriate offset in Yaffss file system,the unnecessary scanning time is reduced when scanning the mounting file system,thereby the mounting speed is accelerated.In latest Yaffs2 file system,we modify the source code of Yaffs2.Meanwhile,we add the support to the modified Yaffs file system in the Linux system,and analyse the performance before and after the modification.Experiments demonstrate the feasibility of the method.关键词
