Im using a magento site with 1.9.1 version and the site is very slow. At googlespeedsight im getting 55-60% at gmetrix its better but its 70% but the page load speed is very slow. There are two main option: Add Expires headers,Leverage browser caching. I've searched a lot but i can only find one solution what is to add some expire code the htaccess file.I did it but Leverage browser caching only increased to 6% from 0%, Expires headers didnt change(still zero). How could i increase this,is there other solution?
I searched on google for days but i only find these as main changes to do to speed up the site.
