How A lot Memory Is My Program Really Utilizing? It appears like such a simple question - but digital memory makes measuring real memory use sophisticated. Shared memory will not be apportioned per course of utilizing it so it is overstated. Resident memory consists of shared memory, so it overstates as well. Digital memory includes resident memory plus data held in swap, which is not in foremost memory. Fortuitously until you are working a Linux kernel older than the last financial disaster, you've gotten a better option: Proportional Set Size (PSS)¹. That is the amount of personal memory the process is utilizing, plus its proportional allocation of shared memory. The file lists every memory block mapped to the method, and its properties. You might wrangle the smaps data with shell code, but you don’t need to! The smem device does that, and it might probably filter/format too. Memory ideas generally is a bit abstract, so let’s take a look at an example.
