Subject: disappointed result on enabling EBS on Samsung small page NAND chip
Date: Fri, 31 Mar 2006 09:46:48 +0800 (CST) [thread overview]
Message-ID: <20060331014718.12468.qmail@web15110.mail.cnb.yahoo.com> (raw)
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
