Hello!
Today, I read about the impact of atime updates on ext3 and possible
approaches on how to reduce that impact by using relatime, a modified version
of relatime - Ingo Molnar posted a patch - or two different states of dirty
inodes, atime dirty inodes which do not need to be flushed soon and dirty
inodes with other changes which should be flushed soon[1].
What would be the impact of atime versus noatime on XFS? What is the
recommended setting for XFS? Are there any plans to implement relatime
logic - maybe even the improved one by Ingo Molnar - into XFS?
I just remounted my partitions on the notebook and my workstation with noatime
for testing and I have the feeling that it indeed does help.
