MessagePacker seems to be slower than Protobuf and JSON in serializing and deserializing ?

[starlight173]

Hello @hirotakan , I am making an experiment test speed between JSON, MessagePack and Protobuf. The experiment is described as below:

Preparing:

• JSON: Encode and decoding using Apple Codable
• MessagePack: Your lib.
• Protobuff: Apple Protobuf
• 3 sets of JSON data (small / med / large).

What I have done:

• Test compress storage
• Test serializing / deserializing

I let the test encoding and decoding the model for 100 times and take the average result.

In the serializing and deserializing in med and large set, the experiment result time is:

MessagePack < Protobuf < JSON

The MP in some test is slower than 300%. This make me so confused. Since most of articles in the internet say that JSON is slowest in med and large set. So I think there's something wrong with my experiment or the dataset is not large or complex enough? One of the article I have seen:

https://medium.com/unbabel/the-need-for-speed-experimenting-with-message-serialization-93d7562b16e4

So I attached the git. Could you take a look on it ?

Thank you and have a nice day @hirotakan

@gloryluu Sorry for the late, thank you for checking polite. If you change the optimization level of the Swift compiler to "-O", I think performance will improve.
