Supernice

Set the I/O-scheduling class, priority and niceness to relaxed values when launching a process.

This was originally a fork of ionice from util-linux.

Running supernice is the equivalent of running both ionice -c3 and nice -n20.

This can be useful to prevent processes from hogging the CPU and the I/O capabilities of a system, with a command that is extremely easy to remember.

If you have ever watched the mouse cursor freeze when compiling a large project, this utility is for you.

Example use

supernice make

• Linux
