Re: How many people regularly defrag their XFS filesystems?

[Justin Piszcz <jpiszcz@xxxxxxxxxxxxxxx>]

Does anyone have any benchmarks for the XFS filesystem contrasted with the 
amount of fragmentation on the disk?  I have spoken with someone who 
believes defragmenting filesystems with XFS is probably a waste of time 
unless there are benchmarks to back it up.  Benchmarks that show that 
performance degrades significantly as fragmentation increases.  Has anyone 
seen or performed any benchmarks? Is it worth defragging XFS filesystems?
