Profiling tool for JSF

[ayouB __]

Hi every one,
 
I'm asking if there is a possibility to do a profiling test for a jsf 
application (like what flash builder does for Adobe Flex), my question is about 
profiling only the prensentation layer build with MyFaces 2.1.6 + Richfaces 4 
not the whole application (as it's known Adobe Flex is Rich Client which it's 
not the case for JSF). If so, is there a tool or a plug-in which does this ?
 
Thanks.
