Yes, i installed from the chaotic aur, thanks again
Okay, there is a my experience with linux-cacule i installed from chaotic-AUR. My laptop at the office feels smoother, more responsive. It's better than linux-tkg-bmq... wow! I must test my personal laptop with nvidia-dkms.

That is often the impression when testing a new kernel I find. However, that is mostly subjective and in the eye of the beholder. Benchmarks are really required to have any validity.

I agree, that's why I asked my colleague to try some time work on this laptop, and he said same experience. (I wasn't tell him anything about kernel change)

It’s hard create a „real“ Benchmark.
It starts at defining a benchmark.
If you got with kernel “x” and kernel “y”,
“x” performance 5% better than “y” at FPS for example, but the input lag, response time and so on.
Every user should try different kernel and make their own decision.
I will create the next week a complete benchmark with the phoronix suite with different kernels each compiled with the same gcc flags and architecture.

I absolute agree, i going to test with my games and after while share gaming experience. Anyway latest nvidia-dkms works without issue with my GTX1050-Ti!

Btw does linux-cacule support OpenZFS? If no, then are there plans to incorporate it? I would love to test ZFS on Garuda, but sadly it isn't compatible with GPL licenses. Thanks, Oracle.
Oh, another test. As I'm compiling veloren-git with high memory/CPU usage I experienced a bit of freezing in my browser, for about five seconds two times. This was not the case with tkg-bmq and zen kernels, but here it's an annoying problem. Maybe there is something special with these two that makes them more resistant against memory overheads?

Will be fixed with next update. Its because the caused by disabled autogroup option.
I testing right now the updated kernel, will be soon in the chaotic-aur. I have also removed the mm-patches since they seems to be not ready for now. Could be also problem.
A feedback when the kernel got updated would be great!
Thanks for your feedback and info.
Edit:
Because ZFS i never used or tested it. need to read more about. if i got any news i will update you

well actually it’s an ivybridge cpu, not a skylake one, lol. Xeons from older generations are dirt cheap. I compiled cacule from AUR, btw
I'm sorry. I over read the the 1270 and there also stands x86v2.
Got today corona vaccination, maybe side effects from it 
Kernel seems stable so far and will be updated to the aur!

Oh, no need to be sorry. I’m also confused by these server CPU’s and struggle to read/write sometimes

This is nice. I'm gonna install it and test it for my gaming session

5.12-8 Changes:
- Cacule patch updated (kernel.sched_max_lifetime_ms=22000 is now default)
- SCHED_AUTOGROUP now enabled on default
- mm-patches got removed (seems to be unstable right now)

Feedback for linux-cacule
- I can play Xonotic and download games on Steam without fps drops! (I always faced this issue with mainline or tkg kernel)
- Xonotic runs more smooth and with lower latency (Hehe more hits on instagib game mode)
- Lower ping, more stable downloading. It makes games more playeble on gabrage Wi-Fi connection.
Anyway: I really recommend compile kernel on your hardware, there is a bigger perfromance gain than you expect.

There is a video on YouTube how linux-cacule can handle gaming, while a CPU is under load (Firefox with Facebook some tabs, Discord, Steam and OBS recording).

If anyone use compiled kernel on your hardware, you should change pacman.conf to avoid kernel update from repositories.
It's simply.
sudo nano /etc/pacman.conf (Yes, you can use vi, vim, nano... it's your choice)
Find line with #IgnorePkg = uncomment this line and write packages, kernel what you need.
My example in pacman.conf
# Pacman won't upgrade packages listed in IgnorePkg and members of IgnoreGroup
IgnorePkg = linux-cacule linux-cacule-headers
#IgnoreGroup =
I compiled linux-cacule on my hardware (Performance benefits, thanks to help @ptr1337 ). I won't update linux-cacule from repositories , that's why my ignorePkg looks like this.
IgnorePkg = linux-cacule linux-cacule-headers

It seems that these packages need some love to maintain them
The exact same package (excluding cpu-arch) was built yesterday successfully by our builder so I dont think there is an issue with the package. Make sure to clean the cache of paru (or whatever tool used) as the patches content changes sometimes, which makepkg cant detect though as the source was already downloaded. Instead, it just tries to verify checksums against a newer version patch which of course fails. 
Linux-cacule-garuda is no longer needed, it was originally setup because the cpu-arch selection was not working correctly with our build tools. As a fix now has been found this package became obsolete (+ AUR staff takes some time to process deletion requests I guess)
