Yes that version breaks full time dual core.

So this begs the questions.....Which is better (for speed and/or battery life), running mostly one core at full speed and then the second when only necessary, or running both simultaneously at half speed? I've seen some discussion on this but it's not real clear.

I'm not sure one has been proven more effective. I personally don't want both cores running all the time...I don't notice a speed increase since clock speed is still the same. Not sure it matters either way, but I will only run a rom that uses second core only when needed

For the most part I agree with this statement. The reality is the device feels faster and will benchmark better. The better benchmarking is what sold a lot of people. The question still remains is if the device finishes processing the data in half the time is it using more battery? I personally have not noticed a drain on the battery and it may even be a little better. If you let the device decide when to use the second core it may never use it.

Also on some ROMs like my Fresh ROM you can just delete the dual core script in the init.d folder and it will return to single core mode.

Ok, I have side questions that pertains to this topic.

If we can enable the second core in init.d when the phone boots, AND it actually does useful work then HTC would have had to have put effort into supporting that in their kernel because ASOP Gingerbread does not naively support dual core, right? So that makes me wonder why HTC shipped the 3D with dual core inactive! Unless I'm flat out wrong somewhere HTC must have had a reason, and the only things I can think of are race conditions and battery life.

Full dual cores oc to 1.8 keep my phone nice and warm in the winter

Our CPU was not designed to run this way (asynchronous CPU). That is why it is not active all the time. Now Nvidia Tegra processors (synchronous CPU) are designed to run dual core all the time. That also seem to produce better benchmarks.

HTC kernel is designed to run the way the processor was designed. HTC would not override the CPU specs like we would just to make the benchmark better. The theory is that asynchronous CPU would have better battery life. Reality is most XDA members only care about benchmarks so they can show their friends.

While I agree with you in principle, I do have both cores active at all times. I have not noticed any difference in battery life. Yet I have noticed a difference of quite a bit less lag while loading applications and flipping through screens than when CPU1 is idle.

Does it really matter in the long run daily use? Not really. It's a fun tweak and I learned something new by utilizing it.

I did not get a truly noticeable difference in benchmark though.

Is there a Kernel that Supports Dual Core for the 2.3.5 Roms (HydroBliss_3.5)?

Not sure which, but I can tell you that I am running this 3.5 rom and both cores show active.
