large response with uncomment HTML - sourcecode

Hello,

I have an application in webdynpro with a performance problem.

A simple transaction take between browser and SAP 3sec. 1sec on SAP-Side and 2sec for what ever. I checked the response with the tool WD_TRACE_TOOL.

The size of the reponse is between 130kByte and 230kByte.

The biggest part of the response is comment out.

Example

<span id = "body">
<span id="sapwdssr..main_span">
<span id="delete"></span>
<span id="insert"></span>
<span id="update">
<span id="400EEF5FD53D3CA0E10000000A1552AC"><!--  --></span>
<span id="sapwdssr..main_span">
<!--<div id="WD01-r" style="width:100%;"><table cellspacing="0" cellpadding="0" class="urGridLayout"
[...a lot of HTML Sourcecode]
</div>-->
</span>
...

Why is a lot of source code between <!-- and -->?

Regards

Maik Sturm
