# goto eval benchmark
Compare switch case, computed goto, tail calls, and regular goto + local switch
in benchmark. Compiled with `gcc` and `-O3` for my machine
(`11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz`/`4 cores`/`64gb ram`).
```
g++ -o eval_bench -O3 main.cpp
```
Ran `100` iterations with 5 samples.
```
$ ./eval_bench --iters=100 --samples=5

Not sure why the tailcall version isn't faster than baseline.
