Performance monitor

A tool which tells you a lot about what is going on in your system.

You can see a hell of a lot disk I/O is going on at startup.	Playing audio using J River.

In the second graph you see what happens when playing audio.

In this case I'm using the J River MC14 memory playback option.

Memory playback loads the entire audio file in memory so no HD access during playback

If I have to believe the resource monitor:

- the audio file access the hard disk with a stable rate of 85000 B/s

- other programs accesses the HD as well

So before you post on a audio forum about the great improvement in sound quality you obtained by using memory playback, check the performance monitor first!
