Ah yeah, I see now. I was used to seeing Mean run both cores more often. This one seems to take more to get the other core to kick in.

There is also a option in the power saving settings, to run the phone only on one core. If you don't want that, make sure it isn't checked off.
So we are stuck with a single core for the moment? MeanRom seemed to do well running both cores, but I like all the customizations available in this ROM.
Or is there something in Viper Control that runs both cores?
It's stock in the Linux kernel, has been since the dual core phones came out.
The kernel has a process called the scheduler.
Android (Linux) is multitasking.
The scheduler not only controls which tasks get to take turns using cpu time, it also schedules tasks to go to whichever core it makes sense to go to, to balance the workload.
The big deal about ICS is that it stepped up to the rev 3 Linux kernel and its scheduler is better with multiple cpu cores.
All this is inherited from the Linux desktop legacy.
Your running both cores more often than you think with just stock.
And the S4 includes a new advantage - when a cpu core is not running, it draws zero power.
So, yes, when your phone is idling or just doing very little, a single core at minimum speed is all that's required anyway.
~~~~~~~~
How the two cores don't work with the stock kernel: they don't work like buckets.
It's not, ok one is full get the next bucket.
Here's how they work: the load is distributed at all times as much as possible.
~~~~~~~~
You can force both cores to always be on - but if there isn't a job requiring much of anything, then all you're doing is wasting power, and bypassing all of the design against that.
If you have stuff that runs dual-core a LOT, then, yes, you may see improvement not having to deal with switching them on/off.
But a blanket guarantee that a dual core mod is a good thing for everyone?
Personally, I disagree.
~~~~~~~~~
Can kernel devs provide a dual core mod with better scheduling?
Yeap, I believe so.
You'll have to check with the various devs to see what all they include and what all they were going for.

Was wondering if anyone had some feedback running the ROM de-sensed?
I find Apex to be super smooth with this running over Sense, don't know if I want to reflash without it or leave it be (assuming 4.1 will make it even better)

I enjoyed Charmeleon de-sensed (a bit) and have been meaning to do that here - I just keep spacing it.
It was an installation option you may have missed.
The installation words were not 100% clear for everyone, I think.
Run the tool as shown in its own thread, linked in our sticky to get it, or re-run their installer without wiping to get it.
100% sure on the first part, pretty sure on the second part.
The 100% part comes from the guy who wrote the fix.

perfect time to ask a question I've always had that will splash a lil milk back behind my ear just when I thought I was comin up....when you say "linked in our sticky", you mean one of the threads marked sticky is where I'll find the tool, somewhere in there????
WAIT!!!! don't answer that....hopefully I made it in time to save myself from demotion....I figured it out......don't judge me...

Does Viper have a setting to make the phone roam only line MEAN does?

I don't think so (can't check I'm on cm10), but you should be able to add it in manually. Let me look for the file

What would be the advantage to this? Better Verizon signal strength? Doesn't roaming crush your battery?

I have horrible reception @ home. So being able to roam would help with that problem.
If it's just at home, you may be able to talk Sprint out of a free airrave.
Too much roaming and they'll drop you.

Hasn't been a problem with the LTEVO but the 3D was constantly roaming, over 50% of the time which I just had to learn to live with, but they never dropped me.

They will only charge you for unused unreturn equipment. the airave is awesome I love mine.

This sentiment seems to vary widely, the one we had at our shop was a complete joke but other people say it is the best thing since sliced bread. Not sure what the differences or problems are but I would love to find out.

it hooks up to your dsl / cable internet and acts as a mini tower. I went from no bars at all inside the house and maybe a bar outside to 5 out of 6 bars inside and several outside.
SamuraiBigEd - I've heard of others having issues as well. Seems location can have a lot to do with it. Apparently I Have mine in an ideal spot in a residential neighborhood. Even in an ideal spot in a commercial area would seem to have its drawbacks such as other signals that it has to compete against. I bet the physics of the whole thing would grab my attention for atleast 10 minutes but after that my adhd would kick in and they would loose me
These are far and away the settings for best performance that I have found -

Kind of irrelevant to this ROM, or the discussion about minfree settings for performance considerations.
When that one is ready for me to entrust my business with, I'll chat with you about it in that thread.
Meanwhile - please resist or post what they use use for their settings.

What app are you using? I downloaded minfreemanager and it looks nothing like that.
System Tuner, instructions above (earlier try on settings shown there).
It goes into effect after the post boot initialization, that's why I decided to give it go.
