Ubuntu has reported that MySQL can be a significant source of power consumption:

This kind of makes sense to me, since I know that InnoDB has a main thread which wakes up every second and tries to do work.

It might be an interesting feature request to offer additional configuration which wakes up less frequently, but potentially does more work?

(The aim here is to offer developers a nicer environment on laptops).

How to repeat:

Suggested fix:
Feature request to have additional configuration.

Besides developer laptops it might also reduce CPU contention on a shared virtual machine platform.

This could also make sense in a (almost) MyISAM or NDB only setup.
