After part 2 I received a couple requests to add in a couple other rust serialization libraries. So one thing led to another, and now I’ve got a benchmark suite I’m calling rust-serialization-benchmarks. Really creative name, eh? This includes all the other benchmarks I referred to previously, as well as capnproto, msgpack, and protobuf.
| language | library | format | serialization (MB/s) | deserialization (MB/s) |
|---|---|---|---|---|
| C++ | rapidjson | JSON (dom) | 233 | 102 |
| C++ | rapidjson | JSON (sax) | 233 | 124 |
| Go | encoding/json | JSON | 54.93 | 16.72 |
| Go | ffjson | JSON | 126.40 | (not supported) |
| Go | goprotobuf | Protocol Buffers | 138.27 | 91.18 |
| Go | gogoprotobuf | Protocol Buffers | 472.69 | 295.33 |
| Go | go-capnproto | Cap’n Proto | 2226.71 | 450 |
| Go | go-capnproto | Cap’n Proto (zero copy) | 2226.71 | 1393.3 |
| Rust | serialize::json | JSON | 89 | 18 |
| Rust | rust-msgpack | MessagePack | 160 | 52 |
| Rust | rust-protobuf | Protocol Buffers | 177 | 70 |
| Rust | capnproto-rust | Cap’n Proto (unpacked) | 1729 | 1276 |
| Rust | capnproto-rust | Cap’n Proto (packed) | 398 | 246 |
I upgraded to OS X Yosemite, so I think that brought these numbers down overall from the last post.
