Question regarding tuned profiles and elevator deadline
Issue
- On all the "performance" related tuned profiles (thoughput/latency performance and enterprise-storage), the elevator is set to deadline. The implication then is that if you are concerned about performance that elevator should be used across the board. Would there be any reason to use CFQ under such a configuration ? If deadline is more efficient, it could lower powerdraw by getting the data the CPU needs faster thereby letting the CPU sleep more once its work is done.
