Following on from my previous test, I have now included JsonFx and as well as the Json.Net BSON serializer in the mix to see how they match up. The results (in milliseconds) as well as the [...]

Considering a very simple finite state machine (FSM) such as a code lock which requires you to enter a 4-digit numeric code and upon which will open the lock for a brief few seconds. Such a FSM have two states: Locked and Open. Every time a key is entered it checks the sequence of digits [...]
