Thanks for the suggestions! I ran 4 subsequent instances of LLR --- assigning affinity to CPUS 0, 2.

The time increased by about 0.120 ms which I guess makes sense given that more cores means slower clock speed.

I loaded up 4 instances running on CPUS 0, 2, 4, 6 and the time per bit almost doubled --- a (0.380 ms. increase).

I think Paul is right --- running four threads on one instance seems to be faster than running 4 instances single threaded.

I would think that with larger number of cores, say 12 or 16, the latter might become slower?
