Doug Cutting commented on AVRO-1277:
------------------------------------
# Yes, the standard approach is to run tests from Perf.java with and without a
patch.
# You're right. Maybe we just need to live with the replicated logic here.
> Improve performance of reflection-based serializers

> I've played a bit with Avro serialization based on reflection, i.e. with the
> classes from org.apache.avro.generic package.
> It works fine in this mode, but is rather slow compared to such frameworks
> like protostuff or kryo.
> Quick look at the source code has shown that a lot of reflection-based
> operations and class lookups are not cached. And such operations are usually
> pretty expensive when executed by a JVM.
> So I changed some of org.apache.avro.generic classes, introduced caching and
> a few other optimizations. Now it seems to perform much better.
