Question about Tapestry 5.0

[Vinicius Carvalho <vi...@gmail.com>]

Hello there! It's been a while since my last post, I tried to catch up, but
after reading over 500 topics I gave up ;). I was checking Tapestry 5 site
(Wow it changed so much that I could not even recognize it as Tapestry ;) ).

One thing that intrigues me is the use of DOM from the MarkupWriter.
Wouldn't it degrade performance?

Regards

Tapestry 5 performance has been really good, for the trival demo apps I've
put together so far.

Tapestry 4 could probably be optimized a bit more; for example, it uses a
lot of StringBuffers which are pretty slow.

The overhead of the DOM is not so great, and there will be a lot of room to
optimize.  It's pretty streamlined compared to, say, Dom4J.

It also makes things a lot easier to code since you can randomly access any
node in the tree.  This simplifies the complex relationship between Label
and TextField; the Label can wait unti after the TextField renders in order
to determine the correct value for its @for attribute.

Most requests are taking under 4ms, and that includes the time to check for
invalidated files (in production, that check will occur less often).

Code is coming together on it, but there's so much more to do, including
localization, assets, JavaScript support, the rest of the form components
client- and server-side validation, invisible instrumentation, etc.
