How does it work
Clone this wiki locally
ulatencyd has 3 different parts:
- core, which does process parsing, building a process tree, etc
- rules, which categorize the processes, analyze the system etc
- the scheduler, which uses the information collected by the core and rules to make decisions on the processes
Some settings are adjustable in
/etc/ulatencyd/ulatencyd.conf and the cgroups that will be used can be changed
The core listens on the kernel when new processes are spawned or exit and runs the rules an scheduler on them. Additionally, a full iteration is run every 10 seconds on all processes. This is required for example when flags, set on a process expire and the scheduler will make another decision.
The rules and the scheduler can be adjusted by the user to his wishes.
