Introducing {yyjsonr} a new, fast JSON package - Fastest(?) JSON parser for R?
* ~2x to 10x faster than {jsonlite}
* supports both read and write
* ndjson support (evolving)
If you're in the market for fast JSON and have particular requirements get in touch! (file a GH issue, toot me, etc)
See github & pkg docs for benchmarks and usage.

The 'JSON' format is ubiquitous for data interchange, and the 'simdjson' library written by Daniel Lemire (and many contributors) provides a high-performance parser for these files which by relying on parallel 'SIMD' instruction manages to parse these files as faster than disk speed. See the <<a href="https://arxiv.org/abs/1902.08318" target="_top">arXiv:1902.08318</a>> paper for more details about 'simdjson'. This package parses 'JSON' from string, file, or remote URLs under a variety of settings.
@jimhester there's a couple of benchmarks on the GitHub README.md which include rcppsimdjdon.
yyjsonr appears same speed or faster**
** caveats: On my machine, using default arguments, for the test cases tried, etc
