It is true in my experience to say that tags mode is deathly slow - I 
don't touch it if I can possibly avoid doing so.

OTOH there might well be an improvement to be had in inband tags mode if 
you enable yaffs's own ECC on the tags and teach it to make a partial 
page read of just the tags area. However I'm concentrating on large page 
devices for the time being, so don't have any time to look further into 
this.
