nlyan opened a new pull request #868:
URL: https://github.com/apache/avro/pull/868


   Avro currently constructs map and vector elements on the stack, decodes in to \
them, and then *copies* the resulting values in maps and vectors.  
   This results in a lot of unnecessary memory allocation when decoding. In my tests \
I was able to get a tight loop of Avro decode operations (reusing target objects) to \
me malloc free with these tweaks, and close the performance gap with Protocol Buffers \
3.
