Can’t really say what’s going on here without seeing some code.

  Well the code is the same for all of them (but when using a bool map we assign true instead of empty struct). So we run this code inside a benchmarking function: m := map[int]interface{} // or m := map[int]struct{} for i := 0; i < t.N; i++ { m[i] = struct{}{} } edit: fix code.

    I'm speculating, but sizeof(bool) == 1, sizeof(struct{}) == 0 and sizeof(interface{}) == 8, so might be as simple as that. https://play.golang.org/p/5acy87JLD3i https://play.golang.org/p/5acy87JLD3i

      Yup that well could be it!
