shell_global_get_memory_info() is a new function which extracts a few global counters we have already, namely glibc's mallinfo, spidermonkey's JSGC_BYTES, and gjs' counters for boxed/object/etc wrappers. There is some slight overlap with perf; ultimately though I'd like this function to do some more extensive analysis, so it wouldn't be quite the same. perf is going to be mainly concerned with how big the whole process over time is; memory_info is for debugging memory leaks. https://bugzilla.gnome.org/show_bug.cgi?id=650692
