Optimize and Monitor Your Linux System’s Efficiency With Stacer

Over time, operating systems tend to become sluggish if not properly updated and maintained. Although Linux devices will perform slightly better than Windows in the long run, a slight degradation in the performance of both operating systems is inevitable.

This is generally due to the accumulation of unwanted cache, startup programs, excessive number of running processes, and junk files that you no longer need.

While popular software like CCleaner solves these problems for Windows computers, Linux has its own counterparts for doing such things. One such application is Stacer, the Linux system optimizer and application monitor.

Install Stacer on Linux

Stacer is an open source Linux application that you can download and use for free without purchasing a premium license. It is available for all major Linux distributions such as Ubuntu, Debian, Fedora, and Arch Linux. The installation process is simple and only requires that you know the Linux distribution you are running.

You can download Stacer from the command line, as an AppImage, or as an installable package for Debian and Red Hat-based distributions from the release page. To install via the terminal, depending on your Linux distribution, you can run the following commands:

For Debian-based distributions:

sudo apt install stacer

To install Stacer on Ubuntu you need to add the official Stacer PPA before you can download the package:

sudo add-apt-repository ppa: oguzhaninan / stacer -y
sudo apt-get update
sudo apt-get install stacer -y

Stacer has a dedicated Processes Section listing all currently running processes. You can keep an eye out for CPU or RAM intensive processes in this list and stop unwanted processes to free up your resources and get better performance.
