Performance Evaluation about Flash File System on Embedded Linux
Shi Xin · Microcomputer Information · 2012
The main objective of this work is to evaluate the performance of the popular embedded file system such as JFFS2,YAFFS and UBIFS-the latest addition to Linux Kernel in the real hardware environment.The result is that these three file system have the same performance of reading operation,but especially during the writing operation,UBIFS has a very bigger advantage than JFFS2 and YAFFS.In real-time systems especially data collection system,there is a large number of data storage of write operation,in this case using UBIFS will to the real-time performance of benefit.
