After discussing with Steve, this is as good as it is going get for sax
processing performance without significant changes. We may be able to get some
minor improvements here or there in the future, but it’ll be only a couple
percent.
Closing this ticket. If it is determined in the future that the significant
changes should be made to improve sax processing performance, a new ticket will
be opened specifically for that change.
> New SAX API causes performance degradations

> Key: DAFFODIL-2400
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2400
> Project: Daffodil
> Issue Type: Improvement
> Components: Performance, SAX
> Reporter: Steve Lawrence
> Assignee: Steve Lawrence
> Priority: Major
> Fix For: 3.5.0
>
>
> The new SAX API caused performance degredations across the board of file
> types. The SAX API is basically just a wrapper around the current API, so
> this is a bit surprising. Need to investigate what is causing these slowdows
> and see if it can be resolved.
