msgpack-lite is a message encoder/decoder that optimizes message sending. However, there are better solutions (purely in Javascript) than msgpack-lite. See that some of them can perform up to 5x better than msgpack-lite. This would result in native Javascript calls being optimized, performing better in a general scenario.

We could carry out some tests within the context of Fivem. Like what was done here
