[Miscellaneous Android Development] martyfender:
First of all, I'm glad you have it working. Did you figure out that you had erased the internal download folder?

You have to be somewhat careful, as some settings in Kernel Aduitor and lspeed can conflict with each other.

first of all, for lspeed, go to settings, apps, lspeed, permissions and turn on storage.

Launch lspeed, approve the su prompt and then go to settings. make sure apply on boot is on, show boot notification, apply on boot notification is set to instant. I turn on use Fahrenheit, since I am in the USA.

Next in main tweaks allow higher YouTube resolution, I set that to the tablets max of 1440, turn on improve scrolling and liquid smooth UI.

I turn off window animation scale, transition animation scale and animator duration scale. however I do this in developer options instead, but my zero setting will also be reflected here. Turning off the above three will speed up the tablet.

Next go to CPU Tuner, set GovTuner to perfomance. Set execution interval to 3 minutes, at least until you confirm on reboot that the setting are being applied.

You can later, after a few reboots, change that to either 2 hrs, or disabled, though I have occasionally, on disabled that the settings are not always reapplied on boot, even though the author has supposedly fix that. I just keep it on 3 min, now.

Next, go to battery and turn on battery improvement, only. I don't fool with the doze settings because if you use, for example aggressive doze the lag when the tablet is woke up from a long doze can be much longer as more google services that run will have to catch up, so to speak.

Next, go to LNET Optimizer (not certain how effective these setting are for our tablet, but choose: big net buffers, net TCP tweaks and net speed+. Then, wifi scanning off, scan interval enter 15 and I leave the others at default. I use openDNS set in my router, so I leave Google DNS off.

Furthermore, go to I/O tweaks, turn on scheduler tuner and partition remount.

Next under virtual memory, turn of the new, experimental feature, dynamic virtural memory, turn on heap optimization, OOM Killer and OOM dump tasks. I'm not certain if these are better off, or on though. Leave everything else at default I'm not certain if these are better off, or on though.

Until recently, I never touched the ram manager, or LMK settings since I did it on my older, Ares 8 with Android 5.1.1. Currently, I am testing mine on gaming. Experiment for your particular uses, I am still experimenting with this setting.

Everything else in lspeed I leave at the defaults.

Kernel Aduitor settings Fahrenheit, force cards, apply on boot, instant

keep the governor on interactive as it is probably the best balance between performance and battery life, as ondemand seems to consume more battery power. Your lspeed govtuner settings applied on boot settings should show under cpu gov. tunables as changed. You can tell this because there will be multiple entries instead of just one number.

I/O scheduler turn on apply on boot toggle here.

read ahead 512 to 1024 Mbs RQ affinity to 2 for both internal and external.

Don't make the read aheads to big or you will eat up some of your available memory.

KSM I now leave this on , but in the past, turned it off. Seems like the tablet is more stable with it on but I may be wrong.

Don't touch LMK, since you set that in lspeed

Virtual memory On my newly refreshed V1.1.1, I am experimenting with the defaults again for a few day.

Usually, though I have set overcommit_ratio to 87 min free Kb to 5000 extra free Kb to 12500, dirty ratio to 20, dirty background to 10

I turn of data sharing.

From recent info I have read, tuning entropy on newer versions of Android is useless and maybe even harmful.

You can use the build property editor to change your screen dpi but you may need to create a new value as I don't see it listed in build properties like my original ares 8 5.1.1 had. On it I had used a build property editor from the playstore, don't remember which one.

Good luck, time to get ready for one more day of work, before I am off tomorrrow.
