[jira] [Created] (DAFFODIL-2045) Performance degredation with hexBinary

Steve Lawrence created DAFFODIL-2045:
----------------------------------------

             Summary: Performance degredation with hexBinary
                 Key: DAFFODIL-2045
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2045
             Project: Daffodil
          Issue Type: Bug
          Components: Back End
            Reporter: Steve Lawrence
            Assignee: Steve Lawrence
             Fix For: 2.3.0


DAFFODIL-2019 modified hexbinary logic so that byteOrder was ignored. It did this by reading in the required amount of data 8-bits at a time. Unfortunately, this resulted in a pretty drastic performance degredation. We should effectively revert that change and instead modify the I/O layer so that it ignores byteOrder, allowing us to read in large chunks of data at once rather than 8 bits at a time.
