Subject [jira] Commented: (TAP5-417) Tapestry 5.0 Performance Improvements
Date Tue, 16 Dec 2008 10:38:44 GMT

    [ https://issues.apache.org/jira/browse/TAP5-417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12656942#action_12656942

Christian Gorbach commented on TAP5-417:

Some thoughts about render performance, my oberservations:
There is a significant difference how Jsp/PHPet al. render pages: the output response can
be flushed during the render phase. And because of the intermediate flushing a Jsp page might
"feel" faster than a T5 render page - which is served and streamed after the complete dom
was constructed and processed.
@see also http://developer.yahoo.com/performance/rules.html - flush the buffer early
I'm not sure if T5 can address early flushing because of different render approaches.

> T5 is as fast or faster than JSP for trivial pages; for pages that render a lot (i.e.,
lots of loops) T5 is not keeping up. It may not (it does so  much more) but we need to narrow
the gap.
