fnrender for crud application slowing

janke

I want to use datatables in php crud application with 3 images for read, update and delete
On my column action i put this code.
[code]
{"bSortable":false,
"fnRender": function(o) {
return "";
}
[/code]
This works fine but the rendering is slowing.
Many thanks for solution to accelerate rendering !!!

Is it specifically that code which makes it slow? If you comment the render function out - is it significantly faster? I would have thought that only for examples with a large number of rows would this be a noticeable slow down for fnRender - particularly given that it's not doing anything more than a little bit of string concatenation. The return is inserted by innerHTML, so I don't have any immediate suggestions... sorry. Perhaps profiling the Javascript will indicate something?

Thanks !!

I read the log apache for each row i have get request for each image
199.242.28.74 - - [08/Mar/2010:10:30:44 +0100] "GET /dpi_images/tools/enable.png HTTP/1.1" 304 - "http://dpi.r.sf.intra.laposte.fr/synthese/ref_impact_nt/index.php?acte=fictrav&pageID=" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)"

.....
I try to reduce rendering time adding caching jquery function
[code]
function submit_el(el) {
$.cacheImage('/dpi_images/tools/enable.png','/dpi_images/tools/update2.png','/dpi_images/tools/delete.png');

return "";
}
[/code]
You can find this function here http://plugins.jquery.com/project/cacheimage
The rendering time is always longer for time i continue to use rendering with text whitout images
[code]
return "Voir Supp Edit";
[/code]
Thanks !!!

My apologise the slowing rendering was becoming from a bad option under IE who was refreshing page for every call.
I resolve in changing parameters of cache in IE.
