  • logo Arch: AUR/minq-ananicy-git. paru -S minq-ananicy-git or yay -S minq-ananicy-git should do the trick. Don't forget to start and enable the service by running sudo systemctl start ananicy.service and sudo systemctl enable ananicy.service.

What's new?

More, updated and better organised rules.

Support for cmdline in rules added. This is particularly useful for applications that share the same name (looking at you Java). See the freenet rule as an example:

{ "name": "java", "cmdlines": ["freenet.node.NodeStarter"], "type": "service" }

This translates to: apply the rule to any process named java, that received freenet.node.NodeStarter as a command line argument. You can add more than one "cmdlines" in case you want to fine tune your rules.

Old description


Ananicy (ANother Auto NICe daemon) — is a shell daemon created to manage processes' IO and CPU priorities, with community-driven set of rules for popular applications (anyone may add their own rule via github's pull request mechanism). It's mainly for desktop usage.

I just wanted a tool for auto set programs nice in my system, i.e.:

  • Why do I get lag, while compiling kernel and playing games?
  • Why does dropbox client eat all my IO?
  • Why does torrent/dc client make my laptop run slower?
  • ...

Use ananicy to fix these problems!


X.Y.Z where
X - Major version,
Y - Script version - reset on each major update
Z - Rules version - reset on each script update

Read more about semantic versioning here


To use ananicy you must have systemd installed.

You can install ananicy manually by:

$ git clone /tmp/ananicy
$ cd /tmp/ananicy
$ sudo make install
$ git clone
$ ./Ananicy/ debian
$ sudo dpkg -i ./Ananicy/ananicy-*.deb


$ sudo systemctl enable ananicy
$ sudo systemctl start ananicy


Rules files should be placed under /etc/ananicy.d/ directory and have *.rules extension. Inside .rules file every process is described on a separate line. General syntax is described below:

{ "name": "gcc", "type": "Heavy_CPU", "nice": 19, "ioclass": "best-effort", "ionice": 7, "cgroup": "cpu90" }

All fields except name are optional.

name used for match processes by exec bin name

~ basename $(sudo realpath /proc/1/exe)

Currently matching by other things is not supported.

You can check what Ananicy sees, by:

ananicy dump proc

Ananicy loads all rules in ram while starting, so to apply rules, you must restart the service.

Available ionice values:

$ man ionice

Simple rules for writing rules

CFQ IO Scheduller also uses nice for internal scheduling, so it's mean processes with same IO class and IO priority, but with different nicceness will take advantages of nice also for IO.

  1. Avoid changing nice of system wide process like initrd.
  2. Please try to use full process name (or name with ^$ symbols like NAME=^full_name$)
  3. When writing rule - try to only use nice, it must be enough in most cases.
  4. Don't try set to high priority! Niceness can fix some performance problems, but can't give you more. Example: pulseaudio uses nice -11 by default, if you set other cpu hungry task, with nice {-20..-12} you can catch a sound glitches.
  5. For CPU hungry backround task like compiling, just use NICE=19.

About IO priority:

  1. It's useful to use {"ioclass": "idle"} for IO hungry background tasks like: file indexers, Cloud Clients, Backups and etc.
  2. It's not cool to set realtime to all tasks. The RT scheduling class is given first access to the disk, regardless of what else is going on in the system. Thus the RT class needs to be used with some care, as it can starve other processes. So try to use ioclass first.
