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):
operation | op | ms | op/s
---------------------------------------------------------- | ------: | ----: | -----:
buf = Buffer(JSON.stringify(obj)); | 82000 | 5004 | 16386
obj = JSON.parse(buf); | 88600 | 5000 | 17720
require("cbor-x").encode(obj); | 161500 | 5002 | 32287
require("cbor-x").decode(buf); | 94600 | 5004 | 18904
cbor-x w/ shared structures: encoder.encode(obj); | 178400 | 5002 | 35665
cbor-x w/ shared structures: encoder.decode(buf); | 376700 | 5000 | 75340
buf = require("cbor").encode(obj); | 7700 | 5008 | 1537
obj = require("cbor").decode(buf); | 3100 | 5119 | 605
buf = require("cbor-sync").encode(obj); | 18000 | 5025 | 3582
obj = require("cbor-sync").decode(buf); | 20900 | 5011 | 4170
buf = require("msgpack-lite").encode(obj); | 30100 | 5012 | 6005
obj = require("msgpack-lite").decode(buf); | 16200 | 5001 | 3239
buf = require("@msgpack/msgpack").encode(obj); | 101200 | 5001 | 20235
obj = require("@msgpack/msgpack").decode(buf); | 71200 | 5004 | 14228
buf = require("notepack").encode(obj); | 62600 | 5005 | 12507
obj = require("notepack").decode(buf); | 32400 | 5007 | 6470
require("what-the-pack")... encoder.encode(obj); | 63500 | 5002 | 12694
require("what-the-pack")... encoder.decode(buf); | 32000 | 5001 | 6398
require("avsc")...make schema/type...type.toBuffer(obj); | 84600 | 5003 | 16909
require("avsc")...make schema/type...type.toBuffer(obj); | 99300 | 5001 | 19856
(`avsc` is schema-based and more comparable in style to cbor-x with shared structures).
Here is a benchmark of streaming data (again borrowed from `msgpack-lite`'s benchmarking), where cbor-x 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 EncoderStream().write(obj); | 1000000 | 533 | 1876172
new DecoderStream().write(buf); | 1000000 | 297 | 3367003
stream.write(msgpack.encode(obj)); | 1000000 | 3179 | 314564
stream.write(msgpack.decode(buf)); | 1000000 | 2151 | 464900
stream.write(notepack.encode(obj)); | 1000000 | 944 | 1059322
stream.write(notepack.decode(buf)); | 1000000 | 1131 | 884173
msgpack.Encoder().on("data",ondata).encode(obj); | 1000000 | 1687 | 592768
msgpack.createDecodeStream().write(buf); | 1000000 | 2084 | 479846
msgpack.createEncodeStream().write(obj); | 1000000 | 1475 | 677966
msgpack.Decoder().on("data",ondata).decode(buf); | 1000000 | 2264 | 441696
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 cbor-x 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
