Hi,
I just want to know if it's normal if when i click on icon responsive to show column hidden by responsive, it takes a long time to display ?
Basically, The more records there is, the longer it takes to display by clicking on the icon +.
Can we improve this?
An example with 20000 rows and responsive enabled : https://jsfiddle.net/alex_froger/Ldqcuf8y/

No - that's not right. It really shouldn't take that long!
The problem here is DataTables'
uniquefunction. Its as fast an implemention as I've been able to get, but its still a double for loop, which means that on large tables the performance is terrible.This is something that I know I need to look into as it effects anything to do with selectors with larger tables (the export for example gets hammered by this).
An object map might be a good option - I'll look into that.

OK - Thanks a lot for the response.
Do you know how long to solve this embarrassing problem ?
I'm not embarrassed. On the contrary, I'm proud of DataTables
. DataTables and its related components are complex bits of software and there will inevitably be areas where they can be improved.
Having said that, try DataTables 1.10.15 which I released yesterday. It contains a change which will significantly improve performance for this kind of interaction: https://jsfiddle.net/Ldqcuf8y/1/
