elisp: Memory Usage
E.5 Memory Usage
================
These functions and variables give information about the total amount of
memory allocation that Emacs has done, broken down by data type. Note
the difference between these and the values returned by
‘garbage-collect’; those count objects that currently exist, but these
count the number or size of all allocations, including those for objects
that have since been freed.
