IIRC the Zen Linux kernel[0] is designed to be more responsive for desktop usage than the mainline Linux kernel. I wonder what metrics these tools would provide on the same exact system except with the 2 different kernels. (also see Liquorix patch set for additional patches on top of Zen[1])
The Anbox support is a big plus. Do you find it is actually fast enough for daily use of any android apps? I have one I use all the time on a tablet, but have not had luck getting a performant solution on my laptop.
I'm using Pop!_OS, I dont know if I have the update installed or not. For me Pop!_OS is the best distro, since Fedora keeps bugging me out. I'm mostly a RHEL person.
I use Zen on a newer Thinkpad T14, but I feel there is a difference. Applications like Firefox and Intellij feel snappier than with the standard Kernel.
