[Yaffs] Mounting behaviour of YAFFS - how it behaves in time compared to JFFS2?

Hi there,

Here's question related to my JFFS2 problems (posted on the MTD-list).

The situation: The mount times of my 32 megs JFFS2 device suddenly 
increased from seconds to (roughly) 9 minutes, after having written some 
files to the device.
The explanation of this is, according to David Woodhouse's best guess, 
that the garbage collector uses all this time "for building up the
node tree for every inode after mounting".
The problem stems (I've been told) from the fact that I have been 
performing "big-file-gymnastics" (11 megs uncompressed - ~3 megs 
compressed) on the device. Possibly along with some small-file actions 
inbetween (?)...

Now my question: Can YAFFS (1&2?) be provoked into showing similar 
"unfortunate" behaviour, or is it handled in another way?

Best regards,
  Martin Egholm
