page faults, that's how many times the OS had to load something into physical ram.

What exactly do you mean by utilisation?

Page faults is your start then

You'll need them pretty much doing the same things for it to mean anything though.
They'll need to be operating on the same demand for memory.

If you get more page faults

by Tony Hopkinson In reply to Load generator

then the OS is having to go back to physical media (swap file probably) to put things in physical ram.

That means the system is thrashing ie it's unloading code from ram it's going to need to reload again shortly.

I would expect a good optimiser to make better choices on what to unload when it gets a page fault.
