Ah, one thing that is only mentioned in the URL is that the "IO count" is in units of 512-byte sectors. In the case of XFS doing logical journaling this avoids a huge amount of double writes to the journal and then to the filesystem. I still think ext4 could do better than it currently does.
I thought about this in context of huge directories when working set of blocks is very large and it doesn't fit journal causing frequent commits. two ideas I was thinking of are: 1) journal "change" where possible 2) compress whole transaction to be written in the journal thanks, Alex - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
