enolib benchmarks

Last updated April 30, 2022

These benchmarks evaluate the performance of all enolib implementations, compared also to the most popular yaml/toml parsers out there. As with all statistics please take these findings with a grain of salt, and feel invited to re-run these benchmarks or point out flaws and possible improvements to the methodology and code (some instructions are provided below the results).

Benchmarks are currently performed on Arch Linux on an Intel® Xeon(R) CPU E5-1650 v3 @ 3.50GHz × 12 (see language sections below for detailed runtime info).

Graphical results

[-] indicates a pure parsing run with unsafe results. (*)

[✓] indicates a benchmark for parsing plus querying and validating the whole document. (**)

░░ 0.123 Shorter bars/numbers indicate better performance.

░░░░░░░░░ 456789 Larger bars/numbers indicate worse performance.

Each ░ represents one second.

How the data is gathered

To see how the measurements were obtained, please take a look at the source of benchmark.js/py/rb inside this repository. To see how the report was compiled, please study report.js inside this repository.

Notes

As you might have noticed, the benchmark figures for ruby are occasionally missing one or two libraries for specific benchmarks – the reason for this is simply that these libraries failed on those respective benchmarks, either by raising an error or even by segfaulting.

(*): The majority of YAML/TOML parsers produce plain object dumps which are inherently unvalidated.

(**): In the enolib libraries a document is validated through querying. If the whole document is queried, the whole document is validated. If only a portion of the document is queried less validation and less memory allocation happens and the performance thereby increases too. The results displayed here represent the (performance-wise worst) case of using all data present in a document.

(***): Some libraries included in the benchmarks exhibit an up to 1000x slower performance compared to the top ranking parsers, these have been partially sampled with up to only 1k iterations, with the total duration extrapolated for the global comparison again.
