Re: Does XFS on hardware RAID5 have perfomance issues?

[Ray Muno <muno@aem.umn.edu>]

I am not using it as a benchmark.  This is just in followup to the person
who posted that they observed kernel compile times that seemed to be 
extremely long on a machine with RAID and XFS. 

I offered this as a comparison running on a machine that has both RAID
and non-RAID filesystems and it shows no difference at all.
