Very Slow charging with DataTable

Hi all,

I use DataTable and some plug-ins for my job (TableTools, ColumnFilter, RowGrouping and HighCharts)
I have more 200 000 datas in base, and in the same page, i have 6 tables, with each more 200 000 datas so.

I can't see my page cause

PHP Allowed Memory Size Exchausted Fatal Error

So I have used

ini_set('memory_limit', '-1');

But now, i don't have the same result : no pagging, no grouping, etc. Or with just 500 datas in base, it's ok.
Furthermore loading page is VERY VERY VERY long.

How can I do ?
