Here are more comprehensive benchmarks. This is comparison with the next fastest JS projects using the benchmark tool from `msgpack-lite` (and data is from some clinical research data we use that has a good mix of different value types and structures). It also includes comparison to V8 native JSON functionality, and JavaScript Avro (`avsc`, a very optimized Avro implementation):

(`avsc` is schema-based and more comparable in style to msgpackr with shared structures).
(note that benchmarks below are several years old)
Here is a benchmark of streaming data (again borrowed from `msgpack-lite`'s benchmarking), where msgpackr is able to take advantage of the structured record extension and really pull away from other tools:
operation (1000000 x 2) | op | ms | op/s
