Why does using hyperthreading cores hurt Kaspa CPU mining results?

Including hyperthreading cores in your kaspa-miner thread count actually lowers your mining output rather than raising it. Hyperthreading makes one physical CPU core appear as two logical cores in your operating system, but both logical cores share the exact same underlying hardware — they are not truly independent. When kaspa-miner assigns work to those extra logical cores, the physical core ends up competing with itself, which reduces overall efficiency instead of doubling it. The practical rule is to set `-t N` equal to your physical core count only, leaving the hyperthreading cores unused.
