> The current implementations of the C# datum readers perform resolution of the
> reader and writer schema on every call to Read. In my tests this was causing
> it to perform poorly when reading a large number of records (slower than
> parsing the same data from delimited text files). It would be more efficient
> if the reader only needed to resolve the schemas once.
