Cgo calls take about 40ns, about the same time encoding/json takes to parse a single digit integer. On my 20 core machine Cgo call performance scales with core count up to about 16 cores, after which some known contention issues slow things down.

That's pretty decent. I'm not convinced about the 16 core limit though, the 12700H has 6 P-cores, 8 E-cores and 6 threads, totalling "20 cores". Not the best chip to benchmark multicore workloads
