So it better I run 2 instances -t 6 --cpu-affinity 0 and --cpu-affinity 1 ?

or just 1 with -t12 ?


PS:

This is what I don't understand:
If I use 1 instance -t 24 I get 480H/s cpu 100%

If i use -t 6 --cpu-affinity 0   I get 280H/s and cpu only at 25%.

Based on this result I expect 1120H/s as total result....but how can I achieve this ?
