> C# reader performance improvement

> Key: AVRO-1438

> Project: Apache Avro
> Issue Type: Improvement
> Components: csharp
> Affects Versions: 1.7.5

> Time Spent: 1.5h

> GenericReader/SpecificReader spend a lot of time comparing the reader/writer
> schema. Remembering the last good match speeds things up about 15% in my
> tests using the avro.pref project for timings. This does not impact the
> DatumReader implementation.
