Description

Problem

Blackbird is a object bytecode precompiler/optimizer that ties into the jackson pipeline and can help with json serialization performance. Reports on the interweb cite 20-40% memory and cpu usage on hard hit endpoints.

This issue is to introduce blackbird into dotCMS and allow it to be used in the defaultObjectMapper when serializing/unserializing data.

Goal

See attached article

Research direction

Review the closed pull requests linked from this issue and any existing serialization tests before deciding how Blackbird should be integrated. Done should include a usable default-mapper integration and evidence that memory or CPU usage improves.
