----------------------------------
Reminder that you said "Patch to follow" :)
> FastByteArray*Stream implementations to replace syncronized JDK

>
> Key: IO-286
> URL: https://issues.apache.org/jira/browse/IO-286
> Project: Commons IO
> Issue Type: New Feature
> Components: Streams/Writers
> Reporter: Paul Loy
> Priority: Minor
> Labels: streams, synchronized
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> In CASSANDRA-2820 I reintoduced the FastByteArrayInputStream and
> FastByteArrayOutputStream to cassandra. These steams are un-synchronized
> versions of the Apache Harmony ByteArrayInputStream and ByteArrayOutputStream
> respectively.
> During my own testing of the streams I found a big difference in the
> performance of the standard JDK BA*S steams and the FBA*S streams on most
> JREs. Then cassandra load testing also showed an up to 10% improvement in
> cassandra performance using these streams.
> Then Thrift has TByteArrayOutputStream which contains a way to get the
> underlying byte[] buffer without a deep copy that would probably be a good
> further enhancement.
> Patch to follow.
