go-overhead-benchmarks

Various overhead comparison benchmarks, for guiding
design decisions when using Go as implementation language.

Interface overhead

Tests the overhead of using interface instead of a native type as a map key.
The interface would be used to abstract both a primitive type and a struct.

String construction

Tests which way of string construction is the fastest.

BenchmarkStringSprintf
BenchmarkStringByteBuf
BenchmarkStringStringBuilder

(Concat < StringBuilder < ByteBuf < Sprintf)
