Reduce size of buffer, stringBuffer and tape.

I believe in future, the JsonValue might be deep copied, thus the size of byte[] and long[] is important.

The performance of DOM Parser and Schema-Based Parser.

Consider the JSON as a tree, the depth I meant is the depth of the node of the tree. For example, ``` // depth 1 { a: 1, b: 2...

The performance of DOM Parser and Schema-Based Parser.

Additionally, consider a real situation instead of benchmark, I believe the classResolver is different when parsing different JSON. So comment out the `classResolver.reset()` can increase the score of benchmark, but...

The performance of DOM Parser and Schema-Based Parser.

I get your point. The number of different schemas should not be large. However, ```java T walkDocument(byte[] padded, int len, Class expectedType) { jsonIterator.init(padded, len); classResolver.reset(); ``` I think in...
