Use the fast-path inlining technique to efficiently reduce the amortized time to call a function.
#### Not using Go diagnostics tooling (profiling [enabling pprof, CPU, heap, goroutines, block, and mutex profiling] and execution tracer) (#98)
#### [Not using Go diagnostics tooling](https://medium.com/@teivah/profiling-and-execution-tracing-in-go-a5e646970f5b) (#98)
Rely on profiling and the execution tracer to understand how an application performs and the parts to optimize.
