I never asked, but before your change how was the single LUn that was
presented tot he LDom configured on the EMC box?
Was it striped over many physical disks? I assumed it was, but if it
was not could help explain the speedup.

Wow, I never would of expected that kind of improvement with a single

Mike,
You didn't tell us is your app is
multithreaded/multiprocess and if each thread does it's own I/O. I
suspect you will not see
much improvements if this is a single thread app.

Mike,
App is multithreaded but the part that does the reads on the 60,000
inode filesystem is single threaded. I have the application admins
testing this now but with my test of doing a simple ls -R | wc -l |
have gone from taken 1 minute 45 seconds down to just under 15
seconds. I would say that this is an improvement.
