Are you saying the reder performance is low in IE, but fine in other browsers? What other browsers have you tried?
Well, i don't have exact data but from just observing it looks slower than in FF. I've only tested with those two browsers.
The showcase for the datatable when switching the tab to the different demos, it appears a bit slower in IE.
In my own app, i've noticed significant slow down, but i need to dig in further to see if it is an issue with rendering, my bean, database, etc...
I was just inquiring if there might have been an issue with IE and dataTables or tables in general.
I'm not aware of any such issues. Please post back with any details that you find.
It looks like the performance issue might be coming from using rich:calendar for too many of my columns. I have 4 columns where the user can enter dates. When i took this out things load a lot quicker, not as fast as FF, but much better than before.
Interesting observation re: the calendar component.
Have you tried an approach where you only activate one row at a time for editing? If the other rows are all plain text, and you only edit one row at a time with rich inputs, it may perform better.
You can't use the Rich:calendar in a datatable due to the horrible performance.
The Rich:calendar is so verbose that IE slows down really badly when there are multiple on the page.
I use jQuery calendar and h:inputText which works much better.
Most richfaces components produce way too much markup to be used in any repeater like a datatable. This goes for popups and tooltips and calendars.
