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
