Are you sure that 4 threads is better that 2 threads for Leela?

2 is the default and on my system it use 1.5 core.

Yes I am sure. You see the results. You can see the CPU and GPU load on my testing stream. The question you need to ask is why others are not tuning Lc0 to their rig for best performance. I guess because then do not know how, or don't want to take the time.

I have seen some very bad setups for Lc0.

I will tell you. If you are setting Lc0 for maximum NPS. You are on the wrong path. NPS with Lc0 is a false flag.

Hi
If NPS with Lc0 is a false flag, which agrees with my experience on Infinity Chess, what exactly are you Tuning it to and how ?
