摘要
本文的主要内容是对目前流行的嵌入式文件系统JFFS2、YAFFS以及最新加入到Linux Kernel的嵌入式文件系统UBIFS在实际的嵌入式硬件环境中进行实时性能的评测和分析。结果显示,在读操作方面三个文件系统具有比较接近的性能,在进行写操作上UBIFS比JFFS2和YAFFS具有非常大的优势。在实时系统特别是数据采集系统中,会有大量的数据保存的写操作,这种情况下采用UBIFS将会对整个实时性能带来好处。
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.
