Optimizing datatables on IE

nsinha

I have a fairly large table rendered using datatables.net 1.9.4 and jQuery. The page is pulling the data asynchronously, and then setting aaData and aoColumns in the datatable initialization. While it displays almost instantly in Chrome, in IE9, it takes 6 minutes to display.

IE's profiler says that 96.7% of time is spent in the offsetWidth function. Where is offsetWidth and when is it called? I can't find a function by that name.

Thank you.

Google finds a lot of comment on offsetWidth. It is not specific to DataTables.

That's true, but it's something related to DataTables, since this profiling is the .dataTable() method.

It isn't a function - its a DOM property. DataTables uses it to get the width of columns.

Try using 1.10 ( http://datatables.net/download - the "nightly") which has a number of optimisations in this kind of area.
