Use of worker_cpu_affinity in hyper-threading context

[Alex]

Hi,

I have one E3-1240 v3 CPU here, which has 4 cores with hyper-threading 
enabled. Currently I have the following setup in nginx.conf:

worker_processes 4;
worker_cpu_affinity 10100000 01010000 00001010 00000101;

In other words, I bind each of the four workers to two (virtual) cores 
(similar to example in 
http://nginx.org/en/docs/ngx_core_module.html#worker_cpu_affinity). For 
a medium-sized frequented site, would you consider this the "correct" 
way? Or would you leave out the worker_cpu_affinity setting and let the 
CPU scheduler do the rest?

Thanks for your help.

Alex
