<a href="http://incubator.apache.org/thrift/" rel="nofollow noreferrer">Thrift</a> is another Protocol Buffers-like alternative as well.

There are good benchmarks from the Java community on serialization/deserialization and wire size of these technologies: <a href="https://github.com/eishay/jvm-serializers/wiki" rel="nofollow noreferrer">https://github.com/eishay/jvm-serializers/wiki</a> 

In general, JSON has slightly larger wire size and slightly worse DeSer, but wins in ubiquity and the ability to interpret it easily without the source IDL. The last point is something that <a href="https://avro.apache.org" rel="nofollow noreferrer">Apache Avro</a> is trying to solve, and it beats both in terms of performance.

Basically protocol buffers (<a href="https://github.com/mgravell/protobuf-net" rel="nofollow noreferrer">protobuf-net</a>) is around 7x quicker than the fastest Base class library Serializer in .NET (XML DataContractSerializer). Its also smaller than the competition as it is also 2.2x smaller than Microsofts most compact serialization format (JsonDataContractSerializer).

ServiceStack's Text serializers are the closest to matching the performance of the binary protobuf-net where its <a href="https://github.com/ServiceStack/ServiceStack.Text/" rel="nofollow noreferrer">Json Serializer</a> is only 2.58x slower than protobuf-net.

protocol buffers is designed for the wire: 

<ol>
<li>very small message size - one aspect is very efficient variable sized integer representation.</li>
<li>Very fast decoding - it is a binary protocol.</li>
<li>protobuf generates super efficient C++ for encoding and decoding the messages -- hint: if you encode all var-integers or static sized items into it it will encode and decode at deterministic speed.</li>
<li>It offers a VERY rich data model -- efficiently encoding very complex data structures.</li>
</ol>

JSON is just text and it needs to be parsed. hint: encoding a "billion" int into it would take quite a lot of characters: Billion = 12 char's (long scale), in binary it fits in a uint32_t Now what about trying to encode a double ? that would be FAR FAR worse.

Does anyone have any information on the performance characteristics of Protocol Buffers versus BSON (binary JSON) or versus JSON in general?

<ul>
<li>Wire size</li>
<li>Serialization speed</li>
<li>Deserialization speed</li>
</ul>

These seem like good binary protocols for use over HTTP. I'm just wondering which would be better in the long run for a C# environment.

Here's some info that I was reading on <a href="http://james.newtonking.com/archive/2009/12/26/json-net-3-5-release-6-binary-json-bson-support.aspx" rel="noreferrer">BSON</a> and <a href="http://code.google.com/apis/protocolbuffers/docs/overview.html" rel="noreferrer">Protocol Buffers</a>.

有没有人有任何关于Protocol Buffers与BSON (二进制JSON)或JSON的性能特征的信息？Wire sizeSerialization speedDeserialization 的速度这些看起来像是通过HTTP使用的很好的二进制协议。我只是在想，从长远来看，哪个更适合C#环境。这是我在和上读到的一些信息。
