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):
---------------------------------------------------------- | ------: | ----: | -----: | -----: msgpackr w/ shared structures: packr.pack(obj); | 254700 | 5001 | 50929 msgpackr w/ shared structures: packr.unpack(buf); | 711700 | 5000 | 142340 require("msgpackr").pack(obj); | 234000 | 5000 | 46800 require("msgpackr").unpack(buf); | 186500 | 5000 | 37300 buf = Buffer(JSON.stringify(obj)); | 297900 | 5000 | 59580 obj = JSON.parse(buf); | 216600 | 5001 | 43311 buf = require("msgpack-lite").encode(obj); | 114000 | 5001 | 22795 obj = require("msgpack-lite").decode(buf); | 40700 | 5006 | 8130 buf = require("@msgpack/msgpack").encode(obj); | 166100 | 5000 | 33220 obj = require("@msgpack/msgpack").decode(buf); | 136500 | 5002 | 27289 buf = require("msgpack-js-v5").encode(obj); | 41600 | 5000 | 8320 obj = require("msgpack-js-v5").decode(buf); | 70200 | 5004 | 14028 buf = require("msgpack-js").encode(obj); | 40400 | 5012 | 8060 obj = require("msgpack-js").decode(buf); | 67100 | 5002 | 13414 buf = require("msgpack5")().encode(obj); | 15800 | 5024 | 3144 obj = require("msgpack5")().decode(buf); | 30600 | 5004 | 6115 buf = require("notepack").encode(obj); | 125100 | 5002 | 25009 obj = require("notepack").decode(buf); | 98600 | 5004 | 19704 require("what-the-pack")... encoder.encode(obj); | 150300 | 5001 | 30053 require("what-the-pack")... encoder.decode(buf); | 100100 | 5000 | 20020 obj = require("msgpack-unpack").decode(buf); | 14900 | 5031 | 2961 require("avsc")...make schema/type...type.toBuffer(obj); | 266600 | 5000 | 53320 require("avsc")...make schema/type...type.fromBuffer(obj); | 370200 | 5000 | 74040
(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 |
|---|---|---|---|
| new PackrStream().write(obj); | 1000000 | 372 | 2688172 |
| new UnpackrStream().write(buf); | 1000000 | 247 | 4048582 |
| stream.write(msgpack.encode(obj)); | 1000000 | 2898 | 345065 |
| stream.write(msgpack.decode(buf)); | 1000000 | 1969 | 507872 |
| stream.write(notepack.encode(obj)); | 1000000 | 901 | 1109877 |
| stream.write(notepack.decode(buf)); | 1000000 | 1012 | 988142 |
| msgpack.Encoder().on("data",ondata).encode(obj); | 1000000 | 1763 | 567214 |
| msgpack.createDecodeStream().write(buf); | 1000000 | 2222 | 450045 |
| msgpack.createEncodeStream().write(obj); | 1000000 | 1577 | 634115 |
| msgpack.Decoder().on("data",ondata).decode(buf); | 1000000 | 2246 | 445235 |
These are the benchmarks from notepack package. The larger test data for these benchmarks is very heavily weighted with large binary/buffer data and objects with extreme numbers of keys (much more than I typically see with real-world data, but YMMV):

This was run by adding the msgpackr to the benchmarks for notepack.
All benchmarks were performed on Node 14.8.0 (Windows i7-4770 3.4Ghz). They can be run with: npm install --no-save msgpack msgpack-js @msgpack/msgpack msgpack-lite notepack avsc node tests/benchmark
