Subject Re: Performance params
Date Thu, 31 Oct 2013 23:46:47 GMT
Kito,

Since Leonardo answered your question, and since subject/title =
performance params, I will go ahead and pass on performance params that are
in my web.xml.

See comments, and the URLs provided below as well. One of the outstanding
Apache/PrimeFaces committers wrote the blog, and I am always happy to share
and/or pass along. Hope it helps.

When you read the context params below, you will see that I'm using high
performance JUEL, OpenWebBeans, and MyFaces...of course. :)
