  Then the reason is that metadata filesystem operations on linux
filesystems are quite faster than on Solaris. You can see the same
effect when exploding a tar archive on a filesystem on both system.

DN: You're onto something here...I just did an un-tar of the file
containing my data (100,000 files) and saw:

Solaris:	11m:28.5s
Linux:	1m26.923s

That's a hell of a difference.  Very peculiar how the sun FS can be so
incredibly slow compared to Linux - and these are reasonably high end
sun Netra machines.  Very strange.  I wonder how reliable the Linux FS
is then if it's extracting the files so fast...does sun have some
ultra-realiable FS features or something I wonder.

Thanks for the reply
