The author doesn't need to know the difference because the task manager is accurate by default. I can still offer you some reassurance:

- The Windows task manager's memory column is the private working set which is the actual memory used by the application minus shared memory (but only shared memory that is currently shared with other processes, not merely marked shared. I.E. it's similar to RES - SHR on Linux but it's more accurate)

- Windows doesn't overcommit memory. Memory that is reserved but unused (not touching all pages) by the app is truly wasted. I mention this because in your other comment you make it clear that you think this is happening. But Windows isn't Linux.

That still isn't a good look.

I’m not sure if you mean a good look for the process or for the author but paging space is just saying “gimme a gigabyte” like saying “gimme a plate” is at a barbecue. The resources themselves aren’t being used at that point.

On Windows over allocating virtual memory (commit charge) is still bad. Unlike on Linux, once the total commit charge hits your physical RAM limit + SWAP limit, Windows will start crashing your applications and refuse to allocate more virtual memory, even if that memory has not been touched yet.

This is also why it is very important to have plenty of SWAP space on Windows, even if you have 64 GiB+ of memory. Because applications love to over allocate commit charge.

As in it's sloppy.

If you're at a BBQ would you take 5 plates just because?
