    Page load time differences between IE and Firefox

    Jiri N.
      Hello all,

      I have a problem with page loading time in IE 8. My page contains tabular form, classic report and some other items. I use some javascript code(placed in HTLM Header section) and also dynamic actions. When I try to display the page in IE I have to wait for 40 seconds (100 rows in tabular form). I realized that the performance is dependent on the number of displayed rows in the tabular form. But decrease the number of visible rows, using pagination, is not an option, because all needed rows should be visible for the users. During the tests I have tried to remove all the JS code and disable all the dynamic action, but the loading time was more or less the same.

      When I try to run the same page in FireFox then it is displayed in 4 seconds!

      I have already try to search some tips or advices how to speed up the page loading, but only what I have found out is, that every web browser is different. The javascript is handled differently, page rendering is done differently and so on.

      Maybe there is something what I have missed, and you experts can help me. Is there anything general what I should check or change to speed up the loading time in IE?

      Thanks in advance!

          Turn the debugging on and run the page in IE. See which processes are causing the slow page load.

            Thanks Denes for your reply.

            I use HttpWatch tool to measure the loading times. Reports are mostly the same for IE and FF. I can see from the report, there is three times shown error 404 Not Found for the items below.

            http://......./images/sRegion-Body.png
            http://......./images/sRegion-Bottom.png
            http://......./images/sReportBG-Standard.png

            The last action which caused 404 error started 2 seconds after the page was asked to refresh. The next action http://......../i/libraries/jquery-ui/1.8.22/ui/i18n/oracle/jquery.ui.datepicker-cs.js started after 38 seconds (hanging in the same place for 36 seconds). Does it mean that the problem is caused by http://......./images/sReportBG-Standard.png action which returns 404 error?

            How can I add the missing images?

              All the images are in the apex installation directory. Are you sure these are missing?

                I find when developing that IE8 is way slower than FF
                I have a large procedure that I edit in SQL workshop regulary it can take up to 60sec to load in ie8 with FF its about 8-10 sec.
                I tend to develop in FF and test in IE8
                will be watching this thread to see if there is a resolve.

                  Hope someone is still watching this thread.

                  The problem with missing images was in the CSS. We use custom CSS style (based on Theme 21 - copy was created and then changed)). But as we realized the the image referencing does not work correctly (but we fixed it already).

                  After the fix, the problem with performance of the page still persists.

                  I tried to use Developer tools from IE to find out the problematic parts of our page.

                  Below are two functions which takes the longest time to run (over 80% of time).

                  dir     http://xxx/i/libraries/apex/minified/desktop_all.min.js?v=4.2.1.00.08
                  m     http://xxx/i/libraries/apex/minified/desktop_all.min.js?v=4.2.1.00.08

                  But I do not know what does it mean and how to fix it (try to fix it).

                  Thx in advance for the advices.
