Did anybody compared performance of s:link and h:commandLink?
I traced my application and found that switching from s:link to h:commandLink produces decrease of RENDER_RESPONSE phase from 520ms to 250ms...
Here is the code:
<s:link view-id="/item.xhtml" action="#{itemManager.viewItem}" value="#{item.title}">
<f:param name="itemId" value="#{item.id}" />
</s:link>
comparing with:
<h:commandLink action="#{itemManager.viewItem}" value="#{item.title}">
<f:param name="itemId" value="#{item.id}" />
</h:commandLink>
JProfiler showed that it looks like param for link is evaluated twice! Once - for getting value, second - for getting its type to product converter
Also there should be other problems, because even double evaluation of item.id could not be so terrible...
And another point - when I tested the same code on small test page without any params of page in pages.xml - the difference was not so significant.
I have a picture from JProfiler with timing for this issue - I just cannot attach it to this post.
