Performance & battery · Measuring Storage Studio's own footprint
How much memory and CPU does Storage Studio itself use?
Short answer: Open Storage Profile and scroll to "Storage Studio's own footprint": a live 15-minute graph of its memory, CPU and system load, plus its on-disk size split into app, caches and data.
You can see it live. Open Storage Profile and scroll to the end: Storage Studio's own footprint shows a graph of the app's memory, CPU and system load over the last 15 minutes, plus its size on disk split into the app itself, its caches and its data.
Those memory and CPU figures match what Activity Monitor shows. In the lighter performance modes the live graph pauses to save resources, but the numbers keep updating.
We don't quote a fixed figure, because it varies with what the app is doing and with your Mac. Your own files are never counted in the footprint. See whether the numbers match Activity Monitor.
