I'm referring to what Activity Monitor app tells me in its memory tab - not the underlying malloc/whatever implementation being used.
It tells me my computer is using 8gb of RAM after a restart and I haven't begun to open or close anything.
Yikes?
- astrange 2y agoIt's very hard to measure memory use because it's reactive to how much RAM you have; if you have more then it's going to use it. That doesn't necessarily mean there are any issues.
- Aloisius 2y agoActivity Monitor counts everything from I/O buffer caches to frame buffers in the "memory used" metric. Add in that MacOS won't free pages until it hits a certain memory pressure and you get a high usage with no desktop apps open. This also means that cleanly booted machine with 16 GB will show more memory used than a machine with 8 GB. Apple suggests you use the memory pressure graph instead to determine whether you're low on memory for this reason.
