Mike Beckerle updated DAFFODIL-2935:
------------------------------------
Summary: EXI output from parse should be faster than textual XML (was: EXI
output/input should be faster than textual XML)
> EXI output from parse should be faster than textual XML
> -------------------------------------------------------
>
> Key: DAFFODIL-2935
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2935
> Project: Daffodil
> Issue Type: Improvement
> Components: Back End
> Affects Versions: 3.9.0
> Reporter: Mike Beckerle
> Priority: Major
>
> Recent performance work showed that EXI, while creating smaller output sizes,
> is not faster.
> This seems to have something to do with using the SAX API.
> Daffodil *should* be able to pass the same element name objects (exact same
> object reference) repeatedly to the start-element and end-element SAX events.
> These strings are stored in the element ERD data structure and should not
> need to be allocated/constructed or even traversed for each element. (If
> we're not storing the exact right string on the ERD, it should be added so
> it's sitting there ready to use.)
> We also don't know if Exificient library is able to take advantage of the
> fact that every start-element and end-element event for the same element
> should be passed the exact same object reference for the string identifier(s)
> of the element.
