They offered me Brendan Gregg tools for Solaris9.

It was just what I needed. I tried psio and prusage and found the poorly
written application
that caused I/O bottleneck. After restarting those processes there was no io
wait at all
on that filesystem.
Original question:
=============
Hi Gurus,
I need a tool to show I/O stats on a per-process basis on Solaris 9.
I'd like to identify how much I/O each process uses to find the program
causing I/O bottleneck.
Best Regards,
Eva
