GENERAL GUIDE TO KERNEL SETTINGS​

some focus on Dorimanx and Boeffla Kernels​

POWER CONSUMPTION VS PERFORMANCE​

GOVERNORS AND HOTPLUGS​

I/O SCHEDULERS, NET CONGESTION, BENCHMARKS​

UPGRADE/DOWNGRADE BOOTLOADERS, RECOVERY​

The purpose of this thread is to put in one place some answers to a LOT of questions on what governors and hotplugs actually do and how to search for your best kernel settings that match your style of phone use.

I also suggest trying the multi-core with low frequency approach for very good performance AND battery savings (yes, you can have both). Frequencies of 1.5/1.7 GHz with an aggressive governor and hotplug should give the same performance as 2.5/2.8 GHz frequencies but with massive battery savings.

I am still in the early stages but would hope others will try this.

This is NOT an ULTIMATE guide, please provide all feedback and comments you see fit, it is all welcome, there are a lot of people with experience and knowledge in this forum.
