S2 in interator really slow

[Greg Lindholm <gr...@gmail.com>]

Struts 2.1.8

I had one page in the application I'm working on which was really
really slow... it was taking 4-5 seconds to render the jsp page.
It's a very simple page, just a list of 10 to 15 items that are
iterated over and each one gets a form with one hidden field and a
button.

It appears it's the <s:form> tag that is is culprit.

Here is the original:

<s:iterator value="#action.userConnectionsPaged">
<s:if test="typeNoConnection">
<div class="section">
<s:form action="AddConnection" theme="simple">
<s:hidden name="userId" value="%{userId}" theme="simple"/>
<s:submit cssClass="button" key="FindConnections.action.addConnection"
theme="simple"/>
</s:form>
</div>
</s:if>
</s:iterator>

Here what I replaced it with to make it run fast:

<s:iterator value="#action.userConnectionsPaged">
<s:if test="typeNoConnection">
<div class="section">
<form action='<s:url action="AddConnection" />' >
<input type="hidden" name="userId" value='${userId}' />
<input type="submit" name="FindConnections.action.addConnection"
value='<s:text name="FindConnections.action.addConnection"/>'
class="button"/>
</form>
</div>
</s:if>
</s:iterator>

That was the only change I made to the page and now there is no
noticeable delay in rendering the page.

Anyone have any idea what would cause the <s:form>  tag to take so
long?   Is there a bug or something with it?
Is there any additional information I can provide to help someone
figure out what is going on?

I've seen reports on this mailing list of slow rendering of jsp pages
but never encountered myself before.

What is this? Did you try with static list (not from DB or so)?
