Hi All,
I am comparing the write performance between JFFS2 and YAFFS2 using the program iozone (
www.iozone.org<
http://www.iozone.org>), which writes files of various file sizes with various chunk sizes.
At 1st glance, JFFS2 looks much better than YAFFS2 :-O, which I can hardly believe! Also, YAFFS2 is very constant over the various file/chunk sizes (positive!).
I increased the YAFFS_N_TEMP_BUFFERS in yaffs_guts.h from 6 to 100 and the write performance values changed enormously, which is obvious. Does anyone have experience with tuning the YAFFS caches? Is modifying YAFFS_N_TEMP_BUFFERS the right place to do it?
Any advice is welcome!
Thank you,
Peter Voser
