I'm sososo scheptic about the 10% latency reduction.

Probably on arch you would have a better latency cause you will use the exact same low-level stack (apart for some pointless "tuning") and you will probably avoid some of their crapware putted on-top wasting resources.

If they minimize the crapware, the expectation could be to have the same latency you would have with arch.

If they really understand what they are doing with the low level optimizations (so rare in the sea of downstream distribution and something I'm so scheptic about) the latency reduction obtained could be in the order of 1%.

10% less latency across different machines just because kernel magic sound really a bullshit claim to me.

But if it works its okay, and if you come from a debian based probably you will see real better performance, but it would be just because its arch and there are less bullshit ontop then zorin-like distros.
