# How can I tell whether Storage Studio is the thing slowing my Mac down?

Check three places, then compare with Storage Studio paused:

1. **Activity Monitor** → **CPU** tab, sorted by **% CPU**. If another app is at the top, that's your answer.
2. **Storage Profile → Storage Studio's own footprint** — a live graph of the app's memory and CPU over the last 15 minutes, matching Activity Monitor.
3. **Job Insights** (from the **More** menu) — a **Working…** pill shows which job is active, such as a move or backup you started.

If you still suspect it, choose **Minimum — core only** in the Storage Profile's performance menu for a while. If the Mac doesn't feel different, Storage Studio wasn't the cause — and **Tuhi** can tell you whether memory, processor load or heat is.
