In the spirit of what-have-you-done, is your question based on performance statistics from Shark?

It's based on dtrace runs before I started. I'm starting with Instruments (Shark) right now.

Particularly the Time Profile (All Thread States) and System Trace techniques?


Yes, I'm looking at these.

Does the File Activity template in Instruments tell you anything about locality of access?

What do you mean by locality of access, files accessed in the same directory?

	Thanks, Joel
