If you run LLR single-threaded at those tiny n-values, you'll get much better production. LLR doesn't multi-thread well when FFT size is smaller than 128K * # of threads.

I'd wait until about n=2 million to bother trying 2 threaded operation.

Running three threads on each did not work out very well. Doing so produced enough heat to cause the CPU to throttle back when the temperature went beyond 85°C. My older i5 might benefit by reducing it to one thread per instance.

n < 2-million. In theory, I could run four instances on this i7. However, I will keep it at two, single thread each.

Many thanks!
