Performance issue sizePerPageList

I have a table with drop-downs , text-areas,check-box so its taking time to load if the number of rows are more than 1000 rows.

Regarding the issue , if i have number of records 2000 and my sizeperpagelist drop down has values 10,25,100,200,all. When i select All , it takes time to render the table , Will you be able to add a spinner on change of drop-down and keep it untill it rerender. I can write the custom code and add spinner but i am not sure when its get rerendered .

Hope you understood my issue . let me know if you have any questions on it .
