    RichFaces performance?

    Barry Fruitman Newbie

      Hi all,

      Would anyone like to comment on the performance of RichFaces components?

      My first experience with RichFaces was the demo at livedemo.exadel.com. I noticed the pages were painfully slow to load but I assumed Exadel had slow hosting. Every page takes a good 5-10 seconds to load.

      We proceeded with our project in RichFaces anyway but our pages our loading slowly too, but we have pretty fast hosting and the server has no load. I've tried the demo apps and my app on several computers, browsers and Internet connections... all SLOW. Even functions that should be 100% client side (like opening a modal panel) take too long.

      RichFaces seems pretty cool but my experience with the performance has been TERRIBLE. The ICEfaces demos run way faster on my computer than the RichFaces demos.

      I don't know what else to do. I'd appreciate any ideas or feedback.


      Thanks in advance!
      Barry

          There are to different issues here:

          1 livedemo.exadel.com host is overloaded with tones of other applications (that have no any relation to RichFaces).

          2. It is not too hard to make JSF application works SLOW if it architecture is not correct.

            First let me say that I like Richfaces and appreciate all of the work you guys put in to let me use a free product.

            However, why is funding for servers so scarce?

            First there is a shortage of storage for snapshots. Hard drives are cheap.

            Now the demo server is overloaded. Servers are cheap.

            For an company that wants to target enterprise level support contracts, you would think Redhat could spare a little funding for hardware.

            Does M$ site pull slow?

              One more known thing.
              Do you use FireFox 2? If so, turn off FireBug and restart FireFox.

                I've never had any problem with performance using richFaces... All the resources and features I use here are pretty quick and the ajas requests are done and completed as son as I can move my eye from the button to the reRendered component... :) I love it!

                But the online demo really s*cks :(
                It take even minutes to load, but one time loaded the performance is pretty good...

                I think all the problems (not much) richfaces has, performance is the smaller of'em

                  dont you get performance problem with modalPanel ? I think that performance problems still exists on some RF components.

                    As best I know, currently, we have no one confirmed case with RichFaces component performance.

                      Guys, a can add that there was confirmed cases in our jira and all of them was solved. So just show us concrete perfomance cases and we'll investigate them for sure ;)

                        I experience some slowdown with modal panels but not on every machine i have available for testing. So i concluded that is not an RF performance issue.
                        For what concern performance in general, i'm currently developing on a pentium IV and all run very fast. I agree with sergey when he says the performance slowdown are more probably due to bad design.

                        I think RF faces performs pretty well (at least in my test environment), even compared with other projects like Icefaces or ZK.

                          hm ...
                          i've got an quite simple tree with "just" 50 elements á 200 childs -> 10.000 nodes

                          every node gots:
                          - some little text
                          - image for a checkbox via h:graphicImage
                          - a4j:support for listenersupport at the image

                          expanding/collapsing nodes and checking the checkboxes takes a lot of time...

                          jprofiler tells me that most of the time is spend by domparsing. i dont know if i handle the tree as intended. here is some code:

                                Hi!

                                Performance of rich:modalPanel is realy a problem.

                                Take a look at http://jboss.com/index.html?module=bb&op=viewtopic&t=133524


                                Just create a BIG data table and show modalPanel over it!

                                Here is some code to reproduce the issue:

                                  guys.. I'm trying to pay your attention again to my phrase "Concrete cases in jira" ;)

                                  So, Feel free to submit your samples to jira.
