physical vs virtual memory

[aulwes]

On the home page, I'm seeing Physical Memory Peak larger than Virtual Memory Peak and Requested Memory Peak. Shouldn't Physical Memory Peak be less than both? Or is it because the addition of the executable itself makes it larger?

Hi, thanks for the report.
I will give a deeper look in the coming days.

I know it could happen shortly for requested & physical because not tracked the same way yet.

Virtual & Physical are asked regularly (not on all allocs) to the OS where requested is tracked by myself on malloc/free.

But it should not happen for virtual & physical which are both obtained in a single request from the OS.

Maybe it rise up when the app make a very short large alloc ? Or if it is a very short run ?

There was effectively a mistake there when using -o dump:watch-dog=true but in theory in the other way as I substracted two times the MALT internal memory to physical one.

If you look on the time chart page, does physical goes higher for a long time or short ?

I made a refactoring of those parts of the code an fix several possible glitches for those measurements.
This is merged in master, will be released soon.
