Default [Q] Huge Lag on my Samsung Galaxy Tab Pro 10.1

So out of no where my Galaxy Tab Pro 10.1 began lagging pretty bad. I closed all of my open apps and the lag persisted. My ram was at about 86-90% being used at one point, but even when I got it to drop the Lag continued.

Does anyone know why this was happening?? and how to fix it next time it happens?
Phones:
Google Nexus 5

Tablet:
Samsung Galaxy Tab Pro 10.1

Install a task manager to see which app or process is using CPU when lagging. Don't pay attention to high RAM usage, that's how Android works,

Reboot the device in Safe Mode and see if it persists.
If you don't know how, hold the power button and long press "Power Offf" and a prompt will appear asking if you want to reboot to Safe Mode.

All 3rd party apps will be disabled (including system app updates I think?)
Device: Moto G (LG-LS980)
ROM: CyanogenMod 11
Carrier: Boost Mobile
Recovery: TWRP 2.6.3.3
If I've helped you, please hit thanks!

You can also use WakeLock detector (https://play.google.com/store/apps/d...detector&hl=cs, http://www.xda-developers.com/androi...-developer-tv/), which monitors the processors and screens wakes by the apps, so you can analyze, if there are any apps, that can potentially cause the problem.
