I have tried a lot of ROM and Kernel. I was on Damian Kernel for a long time and I have used Tornado. I am probably as unbiased as one could be.
Here is what I have tried:
ROM:
SeeArms
Darky's 10.0, 10.1, 10.2
Ficeto JVP, JVR R2
Criskelo V72 to V75
Mar'ts V1
Tornado plus
Obviously stock Froyo and Gingerbread
Kernel:
Speedmod
Darkcore 2.4 to 2.9.3
TalonDev 0.2.1, 4.4.8 to 4.4.15
Semaphore JVQ 1.3.3
DamianGTO Alpha 1 to Beta 3 (All of them)
Tornado Beta 1 and 2
Galaxian SP2
Tegrak
For speed, Damain and Tornado cannot be beat, probably because it is on ext2. However, Tornado is still beta and it was not full stable because of the phone app. I see that Brotuck says he has fixed it now.
To gain speed one has to OC and thats what I am after. My phone will do 1.2 Ghz on all OC Kernel. Recently, I have been able to reach 1.3 with TalonDev 4.4.15 and Tegrak app. Can't reach higher than that. With Tornado I was able to run stable at 1.44 Ghz but again phone app was not stable.
IMHO, once it fully developped, Tornado will be hard to beat.
I have kept a log of my Quadrant scores and contrary to what people says its quite reliable provided you keep testing te same way all the time. For me I do the following:
- Kill all tasks
- Run 3 Quadrants in a row and take the best
- The first one is never the best, 80% of the time, the second one is the best.
My best Quadrant: 3569 (Tornado Plus,Tornado Beta 1 Kernell, ext 2, 1.44 Ghz)
Quadrant on TalonDev: 3226 (Darky JVR R2,TalonDev 4.4.15, ext 4, 1.3 Ghz)
Quadrant on DarkCore: 2573 (Darky JVR R2,DarkCore 2.9.3, ext 4, 1.2 Ghz)
Tegrak and Galaxian were both at about 3000
I am waiting for Tornado to get stable and then I will give it another go. It takes a while to flash Tornado because of the ext2 and because Damian is against 3rd party app to control the OC.
Take it for what its worth and please do not complain about what I wrote. I am an Engineer and I only learn from experience and testing. This is the result of a lot of trial and error and I have tried not to put any personal opinion in it.
One thing is for sure tough, a few months ago there was a lot of difference in the performance of these Kernel and ROM. The more people develop, the closer we get to the limit and there is less difference between Kernel performance.
