[Nook HD, HD+ Android Development] PMikeP:
Wow, is this fast!

So many ROMs, so little time.

I've been using CM 11 nightlies for a couple months now and didn't have many complaints. The usual CM 11 screen flicker problem when charging, some screen black outs (and crashes) on a certain screen in one of my aviation apps. That was about it. CM 11 was fairly fast and incrementally getting better all the time.

CM 11 doesn't have zRAM built in (yet), so I got a lot of app restarts when switching between my high memory aviation moving maps and other apps. But we're trying an experimental zRAM build that's helping with the HD+'s limited RAM.

But then I got a wild hair and decided to look around in the HD forum to see if perhaps Jon had an OC kernel for CM 11. Then I found his build of Liquidsmooth for the HD+. I didn't want to spend a half day wiping and installing a completely different ROM. But I'm glad I did. Wow.

I don't know if it's the overclocking or the other tweaks or all the above, but my AnTuTu score jumped from 17300 to 19100! Thanks, Jon!

(Hotplug governor seems to work best for me in both LS and CM 11. Too early to tell, but battery life doesn't seem any worse in LS.)

I assume that LS does not force the CPU to 100% when running AnTuTu, as CM 11 does. So the 19100 is probably a realistic reflection of performance.

(I haven't experimented with the I/O scheduler yet. I left it set at fiops for now. (Supposedly best for flash memory. Heretofore I've always used Deadline.) I lowered the SD cache to 512, which I found worked best in CM 11. (Using SD Booster to make that change.) FWIW, I enabled the GPU Acceleration and Super Tweaks in LS. )

[FWIW, the word "compiler" is misspelled (twice) in the "Just in Time Complier [sic]" setting.]

I'm happy to report that the screen flickering/crashes are gone when on that special page in my aviation moving map that always flickered - and sometimes crashed - in CM 11. (Requiring that I disabled HW overlays in Developer Options in CM11.) And since I set the "Low Memory Killer" to "Light" in LS, it doesn't kill my apps as aggressively as CM 11 did. (Not apples and oranges, because I was running ART in CM 11, whereas LS implies you shouldn't even try ART.) LS should be even better with zRAM. (And the boot animation is better than the frowning, scary CM alien face. :) )

(Speaking of zRAM, I noticed that someone in the Slimkat forum is running zRAM on Slimkat. I read here that Slim and LS are kinda the same. Is there a way to turn zRAM on it LS?)

I'd be curious to know what the major differences are between LiquidSmooth and Slimkat. Since Jon says LS is "similar" to Slimkat, why does LS exist?

Not much I could find on the web about it. I looked at the Slim home page. It's main advantage seems to be fancy interface stuff. (Although LS has PIE too.) Kinda like a toned down version of PAC? But the LS home page is silent about what makes it better/different.

Like I need to spend another half day wiping and flashing can customizing another ROM. (Titanium Backup is supposed to save data/settings. If it does, it doesn't seem to work for me. I have to reset the Settings on my apps when I restore from Titanium.)

Every trying for that last bit of performance, some questions:

Q: On zip align apps on boot. Should I expect a toast or a notification if an app needed to be zip aligned?

Q: In CM 11, there's a Developer's Option to kill an app with a long press of the Back button. (Seems to be different from swiping "closed" in Recents, in that it completely shuts down the app.) Is there a similar trick in LS?

Q: I updated the host file for disable ads. I got a message that it worked, 0/4. Zero out of Four? That doesn't sound right. Is it?

Q: In CM's Launcher settings, you can disable transitions, stop scrolling wallpaper, etc. But I can't find a way to disable transitions - especially in the App drawer - in LS. (I see ways to change the transitions, but none of the options have "None.") Where are they or what's the trick to kill them?

Q: Last, and this is more of a Slimkat design element, but shouldn't there be a "Close All" button in the Slim Recent panel?
