I noticed that strange golang uses load between cores

i have two cpu six core + HT

core 1-6 low usage
core 7-12 hi usage
core 13-24 very low or not usage

I use a lot of channel
I use a lot of mutex

Do golang no problems with HT or distribution of the cores ?

    I'd say this is expected behaviour, your operating system has kept the workload on a single socket, which is better for cache utilisation.
