Pick up a more recent JFFS2, I believe that there have been some speedups.

I get a lot of feedback that YAFFS is typically a few times faster than JFFS2

FAT is indeed "instant mounting" and uses less RAM because it is not log 
structured. FAT however does have a bad record as far as reliability and 
write speed on raw NAND devices.

In the end you need to look at pros and cons and fit them to your system 
needs.
