GNOME System Monitor as a Linux alternative to Wise Memory Optimizer
Updated
Our verdict
GNOME System Monitor can replace Wise Memory Optimizer for users who need a quick view of current memory usage and process details. It shows real‑time RAM consumption, lets you kill processes, and provides a visual bar chart of memory usage. However, it does not automatically clear cache or offer historical logging, so power users who rely on those features will need additional tools like htop or systemd‑timesync. For most everyday Linux users, GNOME System Monitor offers sufficient monitoring and control without extra configuration.

Does GNOME System Monitor automatically free unused memory like Wise Memory Optimizer?
No. It only displays current memory usage. To free memory, you must manually clear caches or use other tools such as free -m or sync && echo 3 > /proc/sys/vm/drop_caches.
Can I view memory usage history with GNOME System Monitor?
Not directly. The tool shows real‑time data only. For history, use htop, btop, or write a simple script that logs free -m output over time.
Is GNOME System Monitor suitable for non‑experts?
Yes. It has a simple interface with clear charts and a process list. Basic actions like ending a process are straightforward, making it approachable for most users.
