             Summary: Performance for fixed-length textual data formats
                 Key: DAFFODIL-2872
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2872
             Project: Daffodil
          Issue Type: Improvement
          Components: Back End
    Affects Versions: 3.6.0
            Reporter: Mike Beckerle


Users have reported very slow performance on schemas for fixed length textual 
formats such as ARINC 484. (132 column lines, fields are fixed length)

It is reported that it takes minutes to parse 5 million lines. Despite changing 
the schema to use choice-by-dispatch everywhere.
