Resolution: Fixed
> jsf.js: performance improvement by eval call and exists call reduction
> ----------------------------------------------------------------------
>
> Key: MYFACES-2846
> URL: https://issues.apache.org/jira/browse/MYFACES-2846
> Project: MyFaces Core
> Issue Type: Improvement
> Affects Versions: 2.0.1
> Reporter: Werner Punz
> Fix For: 2.0.2-SNAPSHOT
>
>
> While most of the performance now is spend on send and dom replaceElement
> without too much possibilities of further improvements on the client side
> there, we still have speed optimization potential. Currently about 5-8% of
> the execution time is spent on evaling anonymous functions and within the
> exists function.
> We probably can reduce both calls to a big degree by eliminating exists in
> favor of undefined checks where it makes sense (mostly in the module binding
> part)
> and by trying to reduce generally the calls into anonymous functions (which
> comes also with the elimination of exists if called outside of _Runtime for
> instance in _Lang which delegates _Runtime.
> Note there is a 5% speed difference between dev and production due to the
> _ExtLang object which is only present in dev which is just an AOP wrapper
> around _Lang which adds the logging functions missing for prod.
