Performance improvement to BinaryDecoder.readInt()
--------------------------------------------------
Key: AVRO-354
URL: https://issues.apache.org/jira/browse/AVRO-354
Project: Avro
Issue Type: Improvement
Components: java
Affects Versions: 1.3.0
Environment: koli...@koliver-ws4:~$ uname -a
Linux koliver-ws4 2.6.24-26-generic #1 SMP Tue Dec 1 17:55:03 UTC 2009 x86_64
GNU/Linux
Reporter: Kevin Oliver
Priority: Minor
Able to get a 3-7% improvement on Perf -i by creating a specialized version of
BinaryDecoder.readInt() that uses the same code as readLong() but uses ints
instead of long for all its math and bit arithmetic.
The performance improvement is larger on a 32-bit VM (around 7%) than on a
64-bit VM (around 3%).
