> This is a lot of effort for each of the simple native types (Long, Float,
> Double, etc.) type. It is the last thing that is checked. Add a cache for
> these simple use cases.
> I came across this while examining performance of Apache ORC which includes
> an Avro benchmark for comparison. You can see the charts with the change
> implemented.
