VIRT = how much memory the process can access. Includes memory from other libraries, files on disk, memory shared with other processes. Doesn’t really matter if this is high.

SHR = how much of the VIRT memory is shareable. A library might be mapped in and counted under VIRT and SHR but only a few functions are used and these will be the only bits loaded and counted in RES.

RES = how much physical memory it is actually using. This is important.

PR = priority

NI = nice, negative values are higher priority. positive numbers are lower priority. Range is -20 to +19.
