disappointed result on enabling EBS on Samsung small page NAND chip

[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,my
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
