Doug Cutting commented on AVRO-354:
-----------------------------------
I do not see consistent improvements in the ReadInt benchmark, but I do see
consistent, significant improvement in the NestedRecordTest. This is after
applying AVRO-355. Perhaps the shorter call stack causes the integer version
to be inlined in NestedRecordTest somewhere where it wasn't before?
> 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

> Reporter: Kevin Oliver
> Priority: Minor
> Attachments: AVRO-354-results.csv, AVRO-354.patch
>
>
> 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%).
