Wes McKinney created ARROW-6417:
-----------------------------------
Summary: [C++][Parquet] Non-dictionary BinaryArray reads from
Parquet format have slowed down since 0.11.x
Key: ARROW-6417
URL: https://issues.apache.org/jira/browse/ARROW-6417
Project: Apache Arrow
Issue Type: Improvement
Components: C++, Python
Reporter: Wes McKinney

In doing some benchmarking, I have found that binary reads seem to be slower
from Arrow 0.11.1 to master branch. The comparison isn't quite apples-to-apples
since I think these results were produced with different versions of gcc, but
it would be a good idea to do some basic profiling to see where we might
improve our memory allocation strategy (or whatever the bottleneck turns out to
be)
