C# MessagePack implemantion is already exists — MsgPack-Cli, but I was dissatisfied with the performance. Six months ago, I made a serializer called ZeroFormatter. Its performance is very fast and supports infinitely fast deserializer like Google’s FlatBuffers.

For several reasons, I needed a serializer other than ZeroFormatter. One is implementing real-time network communication in games, which means that one data is not large, but it is frequent. It did not take advantage of the infinitely fast deserializer, small binary size and the small memory useage were more important.

I noticed that ZeroFormatter Serializer Architecture can also be applied to MessagePack. It succeeded, achieved MessagePack ‘s compact binary size, cross -platform, and performance.

Also, the LZ4 integration is powerful! Compression and speed were achieved by building in the serializer and tuning each other optimally.

For Unity, I prepared an unsafe mode which can serialize/deserialize Vector3[] in 20 times faster than JsonUtility. It should be very useful for transferring large meshes and coordinates.
