How to post my issue to https://groups.google.com/d/forum/benchmark-discuss

I joined the group but I can't post my question there. Please guide.

I have a class MyClass and I want to measure its ctor performance like this:

static void BM_decimal_ctor_dbl(benchmark::State& state)
{
for (auto _ : state)
{
const MyClass d{123.67};
benchmark::DoNotOptimize(d);
}
}

BM_decimal_ctor_dbl 0.364 ns 0.364 ns 1937088812

I doubted my class performance too good. Is my benchmark code correct?
