Performance Improvement - rc:Toolbar=false & htmlview.css

  • Hi All

    I've noticed a dramatic page performance improvement from using rc:Toolbar=false, resulting in a reduction of about 3 seconds per click to essentially instant (no loading icon), even with several charts and <100 row conditional formatted tables on each page.

    One issue attached to this is that parameters cannot be selected from the toolbar, as it is no longer available.

    So, I started playing with the htmlview.css file in a bid to keep the performance gain but still show the parameters. My initial thought was that the gain was actually due to the parameters no longer showing. I managed to replicate the hidden toolbar through the htmlview.css but without any of the gains.

    Has anyone experienced the same performance improvement with rc:Toolbar=false or, have you been able to modify the htmlview.css file to still show the parameters but keep the performance gains?

  • You are right, the performance gain is related to the drop-downs in the parameters not being populated. This can often be slow, especially if they are query driven.

    Editing the CSS will only hide the control from view in your client, it will not stop the toolbar controls being generated, which will be server side or through AJAX, and populated which is why you are still get the delay.
