It's not much, but it's better than nothing: these files are JSON
representations of the two in-repo benchmark datafiles in the protobuf
repo. The protobuf schemas and the protobuf-encoded payloads were
extracted from Google's protobuf repository (see LICENSE.protobuf),
and the .pbtxt data converted to JSON by hand.
message1.json is the JSON equivalent of
google_message1_proto2's protobuf bytes, in protobuf/benchmarks:
1: string
2: int32
3: int32
4: string
9: string
12: bool
13: bool
14: bool
15: {
1: int32
2: int32
15: string
21: fixed64
22: int32
23: bool
}
17: bool
18: string
67: int32
100: int32
message2.json corresponds to google_message2, again in
protobuf/benchmarks:
2: bytes
3: int64
4: int64
5: {
5: int32
11: float
12: string
15: uint64
31: {
1: float
3: float
4: bool
5: bool
6: bool
7: bool
8: float
}
73: int32
}
21: int32
25: float
71: int32
129: int32
205: bool
206: bool
On my machine, C++ proto uses ~200 ns/message to parse message1 (into a pre-allocated message), and ~120 ns/message to serialise message1. It needs ~116000 ns/message to parse message2, and ~85000 ns/message to serialise it.
