This document serves as the base. Under JSON Pointer #/schemas, it contains 8 schemas.

The program validates these 8 schemas 500 times in a loop. It prints the time elapsed for initialization and then each 20 iterations.

This is the result with 1.4.0:

Yes, that's right: less than 1 second to validate all of the schemas above 500 times.
