Performance degradation for pages with long Nesterenko, Nikolay Mon, 26 Feb 2007 15:47:35 -0800 Hi. I had Struts 2 performance problem for any page with very long <select>, e.g., page with drop-down for all (>2400) cities and all (>2650) zips for the state of California. Such pages took 20-30 sec to be displayed. Logs show that time was consumed somewhere after page generation. Removing optional interceptors didn't help. I replaced jsp with the page HTML source from IE ... the same performance. Extract from the page source is presented below. It doesn't look right for the page having <s:head theme="css_xhtml"/> <script language="JavaScript" type="text/javascript"> // Dojo configuration djConfig = { baseRelativePath: "/custfind/struts/dojo", isDebug: false, bindEncoding: "UTF-8", debugAtAllCosts: true // not needed, but allows the Venkman debugger to work with the includes }; </script> <script language="JavaScript" type="text/javascript" src="/custfind/struts/dojo/dojo.js"></script> <script language="JavaScript" type="text/javascript" src="/custfind/struts/simple/dojoRequire.js"></script> Removing this AJAX related code has fixed the issue.

Hi.

I had Struts 2 performance problem for any page with very long <select>,

e.g., page with drop-down for all (>2400) cities and all (>2650) zips
for the state of California. 
Such pages took 20-30 sec to be displayed. 

Logs show that time was consumed somewhere after page generation.
Removing optional interceptors didn't help.
I replaced jsp with the page HTML source from IE ... the same
performance. 

Extract from the page source is presented below. 
It doesn't look right for the page having <s:head theme="css_xhtml"/>

<script language="JavaScript" type="text/javascript">
    // Dojo configuration
    djConfig = {
        baseRelativePath: "/custfind/struts/dojo",
        isDebug: false,
        bindEncoding: "UTF-8",
        debugAtAllCosts: true // not needed, but allows the Venkman
debugger to work with the includes
    };
</script>
<script language="JavaScript" type="text/javascript"
        src="/custfind/struts/dojo/dojo.js"></script>
<script language="JavaScript" type="text/javascript"
        src="/custfind/struts/simple/dojoRequire.js"></script>   

Removing this AJAX related code has fixed the issue.

Questions:
1. Was AJAX template just forgotten in
struts2-core-2.0.6.jar\template\simple\head.ftl and can be safely
removed?
2. How (not existing in my application) "/custfind/struts/dojo/dojo.js"
managed to take so much time? 

Thank you,
Nick
