    Extra cpu overhead in ajax4jsf

    Yurii Galustov Newbie

      Hello,

      I use Richfaces 3.3.2 components in my project and did stress testing of largest page.

      This page has a few ExtendDataTables, buttons, edit fields and modal ajax forms.

      Lots of a virtual users requested this page and click on buttons randomly.

       

      70% of total time was spend on method org.ajax4jsf.org.w3c.tidy.TagTable.getNodeByAnchor and org.ajax4jsf.org.w3c.tidy.TagTable.addAnchor (See images in attachments).

       

      What this method? How to avoid calling it many times?

       

      Thanks.
