I woun't really be going in advance in this guide because there is just sooo soo many things when it comes to kernel tweaking. I might one day make a follow up guide that will go in to advance but only time tells.
Make sure you have allready followed my guide for unlocking the bootloader and rooting or this guide is pointless.

Lets first argue about kernels.
There aren't many kernels when you talk about this device. There are mainly 2 kernels build and they are only for one model of this phone which isn't really good. If you are not on the A125F you are kindev out of luck with custom kernels for this device, only if you are capabel of building your own kernel which I woun't be expleaning in this guide. I think @physwizz has a guide on how to build a kernel in his telegram, that you will have to go search for. Please don't DM him about that. Anyway continueing on, if you are on the A125F model you can chose between these 2 kernels:
physwizz a12 kernel version 2
physwizz a12 kernel version 2 Based on a125f For OneUI 3.1 (May be unstable for some GSIs) Samsung restrictions disabled More CPU governors Optimised for performance Install from TWRP. Ignore the error message during installation and reboot...

Flashing is simple:
1. Boot in to TWRP
2. Tap on install
3. Find the kernel you want to flash and flash it
4. reboot

ROMS
Woun't talk about this a lot, because it doesn't impact that much but it is still kindev important. If you are able to run a custom rom, I would recomend to do so. Stock samsung isn't really good, there is junk running in the backround which you can disable but It will take you a lot of time and some stuff will break apart. So if you are able to flash a custom rom, I would recomend flashing Linage Os R MOD (LIR)

TWEAKING AND OVERCLOCKING
Once you have setup Linage Os R MOD (LIR) and your kernel of choice you can install either SMART PACK or hKtweaks or anything you really want, it is up to you which one you want to use. hKtweaks and SMART PACK are similar and have almost the same settings. SMART PACK you can get on F-DROID and hKtweaks is on google play (please don't use google play but rather arura store)Go in to SMART PACK and give it root_privlages and allow it to manage files. Go in to CPU options and set the CPU GOVERNOR for BIG and LITLE cluster on PERFORMANCE. Set the CPU MAXIMUM AND CPU MINIMUM frequency on BIG and LITLE cluster on maximum speeds. Make sure all cores are checked and the option applay on boot is checked.
Go in to GPU options and set GPU Maximum Frequency to the maximum you can set. Make sure applay on boot is checked
In battery options you can turn on adaptive fast charging and set it to applay on boot.
Go in MISC and set SELinux State to Permissive, set Force Doze to disabled, uncheck Auto-sync Data, uncheck leases enable, set every CPU sets on 0-7 cpu cores. and set it to applay on boot
Go in to Virtual Memory and enable Z-RAM. Increase Disksize to maximum in Z-RAM options, set the Z-RAM algorithm to lz4.
In virtual memory tunable's increase swappiness to 170.
EDITING BUILD PROP
In smart pack go in to Build prop Editor. And now prepare for editing and adding build prop keys(or if you know what your doing, it will take you 5 min
))))) ). Here is a list of Build Prop Keys to edit. If they don't exist create them.ro.telephony.call_ring.delay=0
ring.delay=0
net.tethering.noprovisioning=true
ro.wifi.channels=11
ro.lcd_min_brightness=40
ro.lcd_brightness=160
ro.config.nocheckin=1
ro.mot.eri.losalert.delay=1000
pm.sleep_mode=1
debug.bt.lowspeed=true
wifi.supplicant_scan_interval=240
persist.sys.purgeable_assets=1
These other ones are optional because they are TCP/IP tweaks
net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.umts=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.hsdpa=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960
