My current settings are :
sio - I/o schedular
Performance - govenor
Performance governor is a "special" one in that it goes to the max. clock speed, and never uses the min., or any frequency in between. You can do that if you want to do benchmarking reliably, but I'm not sure it's good for battery life.
^ That page explains all the governors, but from what I can tell from using Cool Tool onscreen system info app, "lagfree" on Doomkernel seems to be a higher performance governor like you'd expect from the name and not how he or she describes: it seems to scale down only quite slowly from a high clock, I'm guessing to eliminate any possible lag while scrolling the interface that might result if it scaled down quicker. And we don't have anything relating to multiple cores
Anyway, I think I saw you say you were on JokaWild as well. Looking at the Joka init.d scripts the SmartAssV2 parameters are tweaked towards performance and it comes as the default for the rom, so maybe try that as a more balanced option than Performance governor.

I wondered as well if v14 was not as good as v13 3013 for battery life, but better for performance, but 5% in 10 minutes is a lot. Have you tried using the BetterBatteryStats app
to find an explanation? Has it got better just through subsequent use / recharging?
