Summary: performance problems with JSF 1.2
Product: Tomcat 6
Version: 6.0.24
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: major
Priority: P2
Component: Jasper
AssignedTo: [email protected]
ReportedBy: [email protected]
I noticed serious performance problems with JSF 1.2 and Tomcat which seems to
be caused by Tomcat.
The corresponding discussion is available here:
http://marc.info/?l=tomcat-user&m=126607491020706&w=2
Metadata-complete is set to true in web.xml
(see https://issues.apache.org/bugzilla/show_bug.cgi?id=48600)
I deployed two web apps to Tomcat and Jetty and compared performance data.
Average results of 500 calls of a simple jsf page (jsp) with 1000 h:output
tags:
JSF 1.1:
Tomcat 6.0.24: 26ms
Jetty 7.0.1: 35ms
JSF 1.2:
Tomcat 6.0.24: 72ms
Jetty 7.0.1: 41ms
Result:
Tomcat is much faster with JSF 1.1 but terrible slow with JSF 1.2!
One difference between Tomcat and Jetty in the compiled jsp is the
AnnotationHelper.
Compiled method for a single outputtext tag:
Tomcat:
private boolean
_jspx_meth_h_005foutputText_005f999(javax.servlet.jsp.tagext.JspTag
_jspx_th_h_005fform_005f0, PageContext _jspx_page_context)
throws Throwable {
PageContext pageContext = _jspx_page_context;
JspWriter out = _jspx_page_context.getOut();
// h:outputText

_jspx_th_h_005foutputText_005f999 = new

_jspx_th_h_005foutputText_005f999.setParent((javax.servlet.jsp.tagext.Tag)

org.apache.jasper.runtime.AnnotationHelper.preDestroy(_jsp_annotationprocessor,
_jspx_th_h_005foutputText_005f999);
return false;
}
Jetty:

}
_jspx_th_h_outputText_999.setPageContext(_jspx_page_context);
_jspx_th_h_outputText_999.setParent((javax.servlet.jsp.tagext.Tag)
_jspx_th_h_form_0);
_jspx_th_h_outputText_999.setJspId("id2019");
_jspx_th_h_outputText_999.setValue(org.apache.jasper.runtime.PageContextImpl.getValueExpression("1",
(PageContext)_jspx_page_context, java.lang.Object.class, null));
_jspx_th_h_outputText_999.setStyle(org.apache.jasper.runtime.PageContextImpl.getValueExpression("z-index:29202;",
(PageContext)_jspx_page_context, java.lang.Object.class, null));
int _jspx_eval_h_outputText_999 = _jspx_th_h_outputText_999.doStartTag();
if (_jspx_th_h_outputText_999.doEndTag() ==
javax.servlet.jsp.tagext.Tag.SKIP_PAGE) {
_jspx_tagPool_h_outputText_value_style_nobody.reuse(_jspx_th_h_outputText_999);
return true;
}
_jspx_tagPool_h_outputText_value_style_nobody.reuse(_jspx_th_h_outputText_999);
return false;
}
A demo web app is attached
Just call http://<server>:<port>/jsf12/faces/1000hout.jsp
Can the AnnotationHelper be turned off completely?
