I'm testing a JFFS2 filesystem on a compact flash card.  The filesystem 
is almost 1GB in size, nearly the entire flash card.

'mount' works normally, but it takes a while to finish mounting the 
device.  Some write operations, especially right after mounting, also 
take a long time.

Is this behavior normal?  I've read in the archives that larger JFFS2 
filesystems can be slow.  Has anyone else played around with a JFFS2 
filesystem this big, and if so, could you give me your impressions of 
using it?

The answer is - JFFS2 is very bad solution in such a large flashes. And
it is normal it is slow on them. Please, read http://www.linux-
mtd.infradead.org/tech/JFFS3design/node3.html for more info.
