Description

Benchmarks of https://github.com/iboB/huse show unexpectedly long time spent in object creation where the type cache query is practically a hit 100% of the time. It seems that it takes 90us to create an object in the json-parse benchmark there.

We should benchmark (and likely optimize) object creation.

  • Check with a known type: mutate_to
  • Check by mutating to a hit: mutate leading to a known type

Research direction

Start by running the json-parse benchmark from the linked huse project and inspect object creation through the named mutate_to and mutate paths. Compare creation for a known type with mutation to a cache hit; done means the benchmark identifies the cost and the optimized implementation shows an improvement without changing behavior.
