Hello Apex Community,
in our company Internet Explorer 11 (11.0.9600.18665) is the only allowed browser.
Some weeks ago we started a project to replace our old Oracle Forms applications with modern Apex applications.
Unfortunately we are suffering from very poor performance when using Interactive Grids (Apex 5.1.1.00.08). It is not a query problem, but a rendering problem in the browser.
A lot of your Forms are Master-Detail, some Master-many-Details, so we have pages with more than 2 Interactive Grids.
To abstract our problem, I made a page with 4 Interactive Grids, all doing a "select * from emp where 1 = 2" and therefore returning no rows.
When I run the page in IE11 the page on apex.oracle.com (Version 5.1.2.00.08), I wait an average of 17 seconds to load.
Chrome Browser (Version 59) needs less than a quarter of the time (4 seconds).
I know: apex.oracle.com isn't the right environment for measuring performance, so I do not complain the absolute values but the relation between the browsers.
I get the same picture on my (fast) intranet production environment: IE11 is 4 times slower than Chrome, this means 8 seconds for rendering the 4 Grids with zero rows.
So it is awkward to build an application with pages with more than 1 Interactive Grid if your users use Internet Eplorer.
Try out and compare different browsers at https://apex.oracle.com/pls/apex/f?p=2410:1
At the moment our management is re-thinking the replacement of Forms with Apex as I can not say, if and when Interactive Grids will be usable in IE11.
@APEX-Development: Please help! I am an experienced and convinced apex developer an I would be very sorry that I can not use Apex for this challenge!
Kind regards and thanks,
Tom W.
