If that is what you wanted, then create 2 lcore on first physical core.

--lcores (0-1)@0,2@1,3@2,4@3

in short, you are running lcore 0,1 in physical-core 0, lcore 2 in physical-core 1, etc.,

When I instantiate a process with 4 cores, I have 3 worker cores and
one main lcore.

I'm wasting an isolated core (the main lcore) to do nothing.

I want to overcome this and use also the main lcore.
