_Parsing of the AS3257 aut-num object on a 2022 M1 Max running macOS 15.0 (24A335)._
## Methology
For each benchmarked parser, a small executable is created in its native language that parses the AS3257 aut-num object.
With the exception of [RIPE-NCC/whois], the AS3257 object is included as a string literal. To benchmark [RIPE-NCC/whois], the AS3257 object has to be read from a file since Java limits the length of string literals.
## Running Benchmarks
Benchmarks for the parser itself are done using `cargo bench`, while any external parser is benchmarked using [hyperfine].\
To run a specific benchmark execute `just bench-$PARSER-NAME` or `just benchmark-comparison` to run all benchmarks. This will setup required dependencies and run `sudo` so it is only recommended to be used in an isolated environment and is only tested using the devcontainer, other platforms might require additional dependencies to be installed. A working installation of `just` and `cargo` is assumed.
