I have a drupal 7 website. Currently its performance is not good and takes much time to render the web pages. For performance, I checked out in YSlow and came up with some results like move all js files at bottom, compress them and images too etc.
As far as I know its drupal structure to render js first at the head and then it loads the body content. So, Is there any way to move all js files at bottom of the web page in drupal???
