EBS effect

[Peter J Zhu]

hello,
 
  Recently I enanbled EBS with 2.6.15 on Samsung small
  page(oobblock = 512B)NAND chip. The results is as
  following:
  
             Without EBS       With EBS

  Imagesize  31378292B         42379624B

  Mouttime   17s ~             14s ~

  The overhead space is too much while providing NOT
  high mout time improvement But from the thread
  http://mhonarc.axis.se/jffs-dev/msg01763.html, 
  results seems too bad compared with what's claimed. 

  The only diff I can imagine is that he might use big
  page NAND. Any hints are very much appreciated. 

Thanks
Peter
