 Do you, or any of the Redhat people, know if the Red Hat 6 kernel is also 
 recent enough (are those improvements back-ported to RHEL 6)?

I was wondering that too and would love to know which distro/kernel
version have those improvements. The only thing I can find in the
kernel logs is that patch :

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8daaa83145ef1f0a146680618328dbbd0fa76939

which is quite old (but recent when if are talking stable ;))

 If you are using recent Linux Kernels, using the default inode size no longer 
 has any impact to write (PUT) performance through swift.

 I would like to thank the XFS folks at Redhat for letting us know about the 
 improvements in XFS,
  and the XFS team in general for the great work they have done.


Hi Chuck,

Thanks for the heads up.

Thx,
