--------------------------------
Issue Type: Bug (was: New Feature)
> SpecificData.getForClass() cause performance degradation
> --------------------------------------------------------
>
> Key: AVRO-2939
> URL: https://issues.apache.org/jira/browse/AVRO-2939
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.10.0, 1.9.1, 1.9.2
> Reporter: Baruch Shushi
> Priority: Minor
>
> Every generated Object.newBuilder() has downstream call to
> SpecificData.getForClass() since version 1.9.X which is ~37 times slower than
> version 1.8.2.
> This is due to the NoSuchFieldException thrown on every Builder instantiation.
> Sample code to run the benchmarks can be found
> [here|https://github.com/baruchshushi/avro-performance-degradation]
> *JMH results for 1.8.2:*
> Result "com.example.Main.benchmark":
> 24.877 ±(99.9%) 0.153 ms/op [Average]
> (min, avg, max) = (24.426, 24.877, 25.542), stdev = 0.272
> CI (99.9%): [24.724, 25.030] (assumes normal distribution)
>
