[jira] [Commented] (DAFFODIL-2400) New SAX API causes performance degradations

    [ https://issues.apache.org/jira/browse/DAFFODIL-2400?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17627702#comment-17627702 ] 

Mike Beckerle commented on DAFFODIL-2400:
-----------------------------------------

Do we know if this is still true that this is unexpectedly slower for parsing as well as unparsing? 

Now that we have EXI support (Daffodil 3.4.0) there will be more demand for SAX to work efficiently.

> 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.
