Thiruvalluvan M. G. updated AVRO-315:
-------------------------------------
Assignee: Thiruvalluvan M. G.
Status: Patch Available (was: Open)
> Performance improvements to BinaryDecoder
> -----------------------------------------
>
> Key: AVRO-315
> URL: https://issues.apache.org/jira/browse/AVRO-315
> Project: Avro
> Issue Type: Improvement
> Reporter: Thiruvalluvan M. G.
> Assignee: Thiruvalluvan M. G.
> Attachments: AVRO-315-test.patch, AVRO-315.patch
>
>
> The forthcoming patch improves the performance of BinaryDecoder.readLong(),
> readFloat() and readDouble().
> The test-patch has a command-line program Perf in org.apache.avro.io in the
> (test part of the source directory) which tests the performance of readInt()
> (which calls readLong()) readFloat() and readDouble(). On my machine, the
> patch improves the performance by 10% for readInt() and about 50% for
> readFloat() and readDouble().
> The idea is to unroll the loops in readLong(), readFloat() and readDouble().
> There is a small change in doReadBytes() which checks for most common
> condition before less common ones.
