Scott Carey commented on AVRO-557:
----------------------------------
Actually that fixes it.
Perf.java had some inconsistencies. I have corrected those and refactored the
class a little. There is still some work to make it more consistent but the
measurements for GenericReader tests are accurate with some changes.
I am working on a patch that includes those changes and measures the
performance drop when Decoders and DatumReaders are not re-used.
I am also considering removing the Google Collections change for now to
simplify this.
I think we may want to include that later, in the form of Google Guava since
Google Collections has merged into that, but should we leave that for another
JIRA?.

> There are big gains to be had in performance when using a BinaryDecoder and a
> GenericDatumReader just one time. This is due to the relatively expensive
> parsing and initialization that came with 1.3. Patch with example code and a
> Perf harness to follow.
