title: Hook after click save button in product page
body: <p>On Prestashop 1.7.5, when I save a product page, it take more than 1 minute which it's a bit long.</p>
  
  <p>I try with a fresh install of PS, and the saving is very fast.
  So I guess it's because a module link to the hook.</p>
  
  <p>Which hook is call when we click on "save" button in the product page?
  Is it only "actionProductSave"?</p>
