Jackson is consistently faster than GSON and JSONSmart. Boon JSON parser and the new Groovy 2.3 JSON parser are faster than Jackson. They are faster than Jackson with InputStream, Reader, reading files, byte, and char and String. Groovy JSON support and the Boon JSON parser are up to 3x to 5x faster than Jackson at parsing JSON from String and char, and 2x to 4x faster at parsing byte.
