Given an application, how can I measure

the amount of data read and written by that application?
the time spent reading/writing to disk?

The specific application is Java-based (JBoss), and multi-threaded, and running as a service on Windows 7/2008 x64.

The overall goal I have is determining whether and why file access is a bottleneck in my application. Therefore, running the application in a defined and repeatable scenario is a given.

File access may be local as well as on network shares.

Windows performance monitor appears to be too hard to use (unless someone can point me to a helpful explanation).

Any ideas?
