How to optimize generated JS for extendedDataTable ?

[fdegrigny]

I have a page containing an extendedDataTable with 13 row and 50 columns but the generated HTML weight is more than 3 mega bytes and takes 17 s to be load ! This is a very poor perfomance and is not really acceptable for the end user.

The analysis of the HTML source shows that the major part of page is the embeded JavaScript.

When the extendedDataTable is replaced by an simple rich:dataTable the weight of the page is donwsized to only 300 kb !

But we need to used an extendedDataTablebecause we need the column's JS resize functionnality.

Is there any options to configure or optimize the code generation to reduce the size of the generated page ?

At first check the performance with 3.3.3 latest snapshot. Also try to turn columns menu off.

But unfortunatelly we must admit that this community contributed component was optimized not much and most of optimization was targetted to 4.x.

Turning off the columns menu helps a bit, it reduce the size by 500 kb.  But is not enough as the result page is still greater than 2.5 Mb

Many lines of JS are here to supports the columns D'n'D functionnality. Is it possible to turn off the D'n'D and still got columns resize one ?

Unfortunatelly such task present in jria but it not solved so you could not turn this off at component level. you could only patch the component on your own.
