> Key: GEODE-6687
> URL: https://issues.apache.org/jira/browse/GEODE-6687
> Project: Geode
> Issue Type: Improvement
> Components: serialization
> Reporter: Darrel Schneider
> Assignee: Darrel Schneider
> Priority: Major
> Labels: performance
>
> A number of places in geode wrap a byte array in a ByteArrayInputStream which
> then is given to a DataInputStream. Because the DataInputStream always
> allocates some byte arrays and char arrays (even if they will not be used)
> this can generate a good deal of extra garbage.
> Geode has an existing class, org.apache.geode.internal.ByteArrayDataInput,
> that can be used to replace a ByteArrayInputStream+DataInputStream and will
> generate less garbage.
