Inefficient ProtobufUtil.fromWrappedByteArray(ImmutableSerializationContext ctx, byte[] bytes) ----------------------------------------------------------------------------------------------- Key: IPROTO-130 URL: https://issues.redhat.com/browse/IPROTO-130 Project: Infinispan ProtoStream Issue Type: Bug Affects Versions: 4.2.5.Final, 4.3.2.Final Reporter: Nistor Adrian Assignee: Nistor Adrian Priority: Major Fix For: 4.2.6.Final, 4.3.3.Final The implementation uses a ByteArrayInputStream that wraps the byte[], and then creates a CodedInputStream around it and this copies the input data to its own buffer. This should have been made more efficiently by building a CodedInputStream directly around the byte[] (which internally uses CodedInputStream.ArrayDecoder and doesn't need a buffer copy).
