Doug Cutting commented on AVRO-753:
-----------------------------------
It would be great to improve our ranking the "thrift/protobuf compare"
benchmark. Currently that has Avro 1.3.2 at about half the speed of Thrift and
Protobuf, but most of the gap is in deserialization.
I like the idea of committing the simpler writeString() optimization first,
then continuing to tune. +1

> BinaryEncoder has not had a performance improvement pass like BinaryDecoder
> did. It still mostly writes directly to the underlying OutputStream which is
> not optimal for performance. I like to use a rule that if you are writing to
> an OutputStream or reading from an InputStream in chunks smaller than 128
> bytes, you have a performance problem.
> Measurements indicate that optimizing BinaryEncoder yields a 2.5x to 6x
> performance improvement. The process is significantly simpler than
> BinaryDecoder because 'pushing' is easier than 'pulling' -- and also because
> we do not need a 'direct' variant because BinaryEncoder already buffers
> sometimes.
