php jquery datatable load issue -

i have table 15000 data in it. while open page, fluctuates many times. i.e. loads entire data first. applies pagination. have set 500 records per page. page load bad. possible load 500 records first instead of load entire data.

please let me know suggestions. thanks

what doing wrong. have use ajax this. datatables supports ajax right out of box.
