[Motorola Droid RAZR] Ohmster:
Thank you Daniel. I really did not realize there was such a difference on 11/07 for XT910 and XT912. One thing I always do is use a combination of killing non-essential or unwanted apps and services with Titanium Backup. Freeze them to keep the dead over flashing more builds, uninstalling when the rom will no longer be updated. (I have not got to *that* point yet.) Then, I beat almost everything to sleep with Greenify Donation Pack. This combination really takes "the slowness" of of almost any rom. Now that I have a speedy rom, I care about stability of the rom itself. Something that does not lock up, lag, or cause issues. THAT was were Build 11/07 really shined best for me. Once I got the rom into the condition where the phone was not really doing much of anything at any given time unless I was running an app or two. Any of the other builds that worked were also pretty fast, but the encroaching lag, FCs, stuttering, or other issues made me drop them. If I did not freeze, uninstall, and beat my apps and services to sleep with Greenify, none of the roms I used would be fast. Except for the very beginning of CM11 when it had almost no features and simply ran a Kit Kat kernel with very basic services.

Kit Kat was very fast for me, the first time I tried it and for a couple of months, maybe, before it got developed. After that, it just got slower and slower and really had me annoyed for a very long time. Worst was when the few experienced members knew enough to severely limit the apps they install and took measures to trim them back, shut things off, and put things to sleep, these guys had roms "that always ran good and ran fast". And here I am, with the same build as them, and mine is slow as a snail! That really ticked me off and it took quite a long time to find a strategy that worked and then put it all into a maintenance and performance guilde.

Brand new smartphones "have power and resources to burn". Something like a new Note 4 or Turbo would not likely need all this freezing and sleeping. With the kind of power they have, they run "normally" without so much pruning. But a Razr has one half or one third the power of a new, good smartphone and simply cannot do this, without "help". IMHO

Have you found a "best rom build" of CM11 for the XT910? Are you actually using these tools to get the rom into a state of where you do not have "Apps Gone Wild!" with Facebook running constantly, and many other apps constantly syncing, checking messages, and keeping the phone awake? So are you doing anything at all to help the rom be fast or just running it, as it, with your apps? :confused:

What I am trying to figure out, [MENTION=1472623]d.casper.b[/MENTION] is whether the XT910 11/07 rom is inferior than the XT912 rom, OR, are you just not bothering with or had time to "reel in the rom" and restrict and limit apps and services from taking over your phone? One thing I do know and that is "Casper" is a pretty laid back kind of guy. (Hammock, dancing girls, and bring me a Pina Colada in a coconut shell drink, please.) Not likely to take extra measures and work if he does not feel like it or it is too much work. LOL! :laugh:

I did not get my rom running smooth and fast like this in a day or two. It took quite some time to figure out what to put to sleep, and slowly upping the amount of things I could put to sleep without negatively affecting the phone. That actually took quite a while. Weeks or a month or more. But once setup, I really do not have to fiddle with it much, unless I start installing new apps and removing old ones. That would change the system and I would have to follow it up by readjusting Greenify to "correct the abhorrent and unruly apps".

You just installed 11/07 not long ago and did not put a lot of time into fine tuning it, yes? Just trying to understand, that is all. I did not think you were using CM11 lately.

Thanks you Daniel, looking forward to the followup reply if you can give one. :)
