Parsing a large (30MB) JSON file with net.liftweb.json or scala.util.parsing.json gives OutOfMemoryException. Any recommendations?

I have a JSON file containing quite a lot of test data, which I want to parse and push through an algorithm I\'m testing. It\'s about 30MB in size, with a list of 60,000 or so e

Try using Jerkson instead. Jerkson uses Jackson underneath, which repeatedly scores as the fastest and most memory efficient JSON parser on the JVM.

I've used both Lift JSON and Jerkson in production, and Jerkson's performance was signficantly better than Lift's (especially when parsing and generating large JSON documents).
