Speed: the validator is-my-json-valid is thousands of times faster then jayschema #47

I've been investigating JSON-schema validators. And contributing to the benchmarks at the JSON-schema validators themisand JSCK. According to the benchmarks included in both themis and JSCK. Jayschema is extreemely slow. And is-my-json-valid is the fastest of all at least 5 times faster than the runner up, and thousands of times faster than jayschema.

Wow that's a big difference...

JaySchema was created at a time when there were very few comprehensive options for JSON Schema. Most validators supported an older version, or only a subset of the current version. Its goal was to be complete and accurate (pass all unit tests).

Although the goal was never to be fastest, it was fast enough for many things, including our internal use cases.

Now the situation has improved and there are other comprehensive validators, which are also much faster. If starting over, there wouldn’t be a need to create JaySchema.

For my use cases it’s still fine—as they say, it continues to work as well today as it did yesterday. But speeding it up would require a significant re-architecture.

I would be glad to link to some of the other validators from the JaySchema README, if someone wants to make recommendations.

I created a benchmark, and a list of what official test are failing for each validator here: https://github.com/Muscula/json-schema-benchmark
