Description

Currently the diff perf logs in NodeObserver does not indicate what type of change was processed i.e. was the change an internal one or an external one.

Having this information would allow us to determine how the cache is being used. For e.g. if we see slower number even for local changes then that would indicate that there is some issue with the diff cache and its not be being utilized effectively
