Excellent Utilities: Ananicy – auto nice daemon


When someone describes their computer feeling slow, it’s typically not computers sporting old CPUs. CPU usage is generally not a serious bottleneck, unless you’re doing very intensive computation. GPU is also rarely a bottleneck unless you’re into heavy gaming, or 4K rendering.

So why do you get lag while playing a game and compiling software, or interact with your KDE/GNOME/MATE desktop. Or find Dropbox reduce your system to a crawl? It’s a combination of CPU/GPU/IO/memory and more.

You want a single daemon to fix these problems. Use Ananicy. It works so great, it’s a must-have utility.

Ananicy offers a huge number of ready-to-use rules for many popular applications, and it’s easy to tweak them, or add rules for other programs. Best take an existing rule as a template and tweak it for any programs you run that don’t already have a rule.

For a complete list of the programs and rules, here’s the rules cache (generated with the “ananicy dump rules” command). As you can see, the applications comes with over 220 rules for both open source and proprietary Linux programs. A lot of care and careful thought has gone into defining each application’s settings.

Ananicy is written in Python. Learn Python with our recommended free books and free tutorials.
