Note: Don’t forget to check out Benchmarks page to see the latest round up of binary and JSON serializers.
Follow on from my previous test which showed that the ServiceStack.Text JSON serializer was the top dog in town, I came across a little library called fastJson on codeplex so naturally I had to test it out and see how it compares to the rest!
So using my SimpleSpeedTester and repeating the same test as before I got the following results:
And graphically, this is how they look:
fastJson was the fastest in serialization and ServiceStack.Text was fastest in deserialization but there is very little separating the two libraries in both cases. Given a different data structure to serialize/deserialize you might end up with slightly different results but at the end of the day the two serializers have similar performance characteristics and both are some way ahead of the other JSON serializers I’ve tested.
Following on from request by @ICooper, I’ve included JayRock in the mix. However, as I had trouble deserializing (serializing was fine) the List<int> with JayRock I modified the test object slightly:
Otherwise, the conditions of the test are as before, and the results are as follows:
ServiceStack and fastJson still offer by far the best performance, especially with deserialization, but this time around ServiceStack proved to be the slight better of the two, why that’s the case with an int instead of a List<int> is beyond me though!
Again, if you’re interested in seeing the test code yourself, you can browse it here on Codeplex.
