# Reniced
|
|
|
|
Helper utility intended to run as a service or as background process (say, in tmux) that can make system more
|
|
respositive under certain type of load.
|
|
|
|
## Why it was made
|
|
|
|
In general case os can handle load well, fairly sharing resources among processes. But in some cases it makes it poorly.
|
|
As an example it can be ill-minded pseudo-security stuff like antiviruses or mediaanalysers that searches forbidden
|
|
content on your mac (due to gov.policies that apple have to accept). Or it can be backup that crawls fs in background.
|
|
|
|
To help resolve such situation this utility was made. Some malicious processes can be reniced to lower nicelevels (say,
|
|
19) and for some good processes nicelevel can be raisen to higher values (-19 if reniced run as superuser or 0 if as
|
|
normal).
|
|
|
|
In some critical cases process can be killed (if you want to know more about it see "man kill" in terminal).
|
|
|
|
## How to build, configure, run it
|
|
|
|
You will need Go lang 1.21 or newer, gnu make, terminal and possibly internets to build this utility.
|
|
|
|
To build reniced just type in project dir
|
|
|
|
```bash
|
|
make
|
|
```
|
|
|
|
this will produce binary named "reniced".
|
|
|
|
Copy to your home directory .reniced.yaml.example as .reniced.yaml and edit it to suit your needs. After you done, you
|
|
can run utility as:
|
|
|
|
```bash
|
|
./reniced
|
|
```
|
|
|
|
if you have no access to superuser or
|
|
|
|
```bash
|
|
sudo ./reniced
|
|
```
|
|
|
|
if you can sudo. That's it.
|
|
|
|
Note: negative niceness values can be set only by root.
|
|
|
|
Note2: MacOS has too tight (or intrusive) security measures, so running something as system daemon is very difficult
|
|
task. Reniced can be run via sudo as daemon or backbround process (say, in tmux). On linux systems usually there is no
|
|
such obstacle and if reniced run from user with id=0, its config should be placed at **/etc/reniced.yaml**
|
|
|
|
## Special "thanks"

|
|
|
To security assholes that disrupt workflows and make this world worse.
