In Windows, are cores 0 and 1 hyperthreads of the same physical core? That would explain your timing exactly doubling.

What happens when you assign the second LLR copy to core 2 rather than 1?

Have you tried not assigning affinity? I've had decent luck just letting Windows utilize the cores- manually assigning affinity does help sometimes, but for this use case I'm not sure it matters for you.
