Description

As we start looking more at performance benchmarks and more generally once Oak starts to get deployed in production environments, it would be really useful if we provided a collection of useful performance metrics in a way that's easy to access.

For example it would be good to have metrics on at least the following:

• Time per MicroKernel read
• Hit/Miss ratio of the NodeState cache
• Time per MicroKernel commit/merge
• Time per each commit hook
• Time per query
• etc.
