Go expression evaluation comparison

I've created an expression evaluation package and wanted to compare it performance against other similar project. So I created this this repository with benchmarks for various packages.

Here is results (lower is better):

Benchmarks are run with the following specs:

goos: darwin
goarch: amd64
cpu: Intel(R) Core(TM) i9-9880H CPU @ 2.30GHz

Basic Benchmark:

Benchmark_expr-16                       184196986              134.2 ns/op
Benchmark_celgo-16                      122053126              187.4 ns/op

StartsWith Benchmark:

Benchmark_expr_startswith-16            81022359               280.1 ns/op
Benchmark_celgo_startswith-16           66076286               327.7 ns/op

Usage

You can clone repo and run benchmarks yourself.

go test -bench=. -benchtime=20s
