Performance it´s more important in development web applications.

I´ve tested Python + Nginx + Tornado Web Server. It´s ok and worked.

is there any sugestion to configurate Nginx + Wildfly + Varnish???

It could be in documentation of Wildfly with some examples or tutorials.

Is there somebody can be indicate or show any example?

I think, it´s one the best way to power of deploy applications Java with tecnologies i sad before.
