Answering my own question, it appears yaffs is fond of having its files distributed in directories.
Tests run last night with 475MB of data in 10000 files spread some 400 directories give me
performance that is acceptable. 4 second mount times, and quick enough I/O to the mounted
device. And mostly I won't have this much data stored, so it's all good.

Thanks for following up with that Rob. Your original post had me scratching my head a bit.

Yaffs stores its drectory structure as a doubly linked list of "siblings", so that means directories with very large

numbers of entries don't get handled particularly well.
