Listen, when you're talking a multi TB or PB file system it *is* an issue 
I assure you.  With disk sizes growing like they are it is only going to 
get worse.  This is a concern for a great many of us.

EXT4 is in a few edge cases faster due to this, but XFS is still very fast 
in almost all other scenarios despite this.

The point of the HPC scheduler is to
keep everyone equally unhappy.
