L Speed - świetne przyspieszenie systemu

Boost now - Use this to drop caches and slightly boost your device (this give a temporary boost)
FStrim now - Trimming /system, /data and /cache partition and reduce lags
Battery Calibration - This option will reset battery stats, read correct values of the battery and show correct battery level
CPU tuner - CPU power save and governor tweaks
Selinux - Change seliux status (android 4.3+)
Cleaner Menu - Use it to clean junk files (.txt .log .tmp), app cache, and much more.
Seeder - Work with device entropy, aim is reducing lags. (seeder won't work with all devices, that is a fact.)
Ram manager - Script that manages low memory killer values, now with profiles
OOM killer - Enable/Disable app killing when device is out of memory
Cache reclaiming - Controls file system cache, and it's "refreshing" rate
Cache allocation - Controls how much percent of physical memory can be taken for caches
Kernel tweaks - Kernel optimizations
LNET Optimizer - Various Net optimizations
Disable debugging - This option will disable unnecessarily debuggers and improve battery life and performances
Disable kernel panic - This will reduce chances of rebooting device when (for example) device go out of ram
Kernel sleeper optimization - Sleeper Fairness is a concept used by CFS which treat sleeping/waiting tasks as if they were in a run queue. This implies tasks which spend most of the time waiting for an user input and such will get a fair share of CPU when they need it. This in an optimization for battery life in standby mode and also responsive UI.
1Kernel same-page merging - This option merge same pages in the ram and free it up. (This option will consume a bit of the battery)
SD Tweak - Increase R/W speed of Internal and external SD Cards
I/O tweak - Increases the Input/Output speed of overall system and makes your device snappier
Zipalign - Zipalign is an archive alignment tool that provides important optimization to Android application (.apk) files. Specifically, it causes all uncompressed data within the .apk, such as images or raw files, to be aligned on 4-byte boundaries. The benefit is a reduction in the amount of RAM consumed when running the application
Fast Charge - Enables fast charging option if your Device/Kernel supports it
ZRAM - Like a SWAP but this is on ram, (kernel must support it)
Wifi sleeper - Improves battery life by making Wifi scan less frequently and at particular intervals
Flag tuner - Disable multitasking restrictions
Better voice call quality - Aims at improving the In-Call voice quality

Improve image quality - Sets the Image Quality to 100% by removing the restrictions of many camera apps (EG. Google camera) which only allow middle Quality.
Faster streaming - Smoother video streaming
Liquid smooth UI (less lag) - Helps reducing OS Lags
Disable logcat - This tweak lets you disable logs for a slight boostin performance
Fast dormancy - The Fast Dormancy technology was introduced to 3G UMTS to save the current consumption of the device by switching between different mobile network modes during poor signal or low signal
Misc L SPEED tweaks - Miscellaneous tweaks to help improve ur device
Assertive Display - Assertive display technology is engineered to adapt to variable lighting conditions, so smartphone users who have come to rely on their devices for video entertainment will particularly enjoy the experience it provides. For instance, bright sunlight, glaring screens and light reflections won’t keep you from enjoying your latest e-book download or streaming your favorite movie. Assertive display technology works by adjusting the gamma or color curve for each pixel on the screen individually, taking into account both the content being displayed as well as the presence and intensity of any ambient light.
