2021 MacBook M1 pro CPU cores 1 & 2 dominant

This is not an issue (hopefully) but more of a question if anyone knows the answer. I just got my MacBook M1 Pro couple of days ago and noticed CPU cores 1 and 2 are dominant almost all the time, all the other cores usually running low unless the CPU is handling heavy processes, but 1 & 2 are usually running high, they can even be at 80% while others around 10% or so. Any reason for this? I have not seen this with any multi-cores before, usually work is closely distributed. Example below:

System: 2021 MacBook Pro M1 Pro, 8 core CPU, 14 GPU, 16GB Ram

Apple has designed their m1 pro chip with 2 efficiency cores and 6 performance cores. So when you are doing lighter tasks it will use the efficiency cores to save power.
