Which JSON library for Java can parse JSON files the fastest? JSON.simple vs GSON vs Jackson vs JSONP
After several tests, here are the conclusions:
Choosing which library to use on the merit of parsing speed comes down to your environment then.
- If you have an environment that deals often or primarily with big JSON files, then Jackson is your library of interest. GSON struggles the most with big files.
- If your environment primarily deals with lots of small JSON requests, such as in a micro services or distributed architecture setup, then GSON is your library of interest. Jackson struggles the most with small files.
- If you end up having to often deal with both types of files, JSON.simple came in a very close 2nd place in both tests, making it a good workhorse for a variable environment. Neither Jackson nor GSON perform as well across multiple files sizes.
