Hello - across 6 sites all v1.5.1 and all using the same template (Responsive All Business - Picaflor Azul) I am getting consistent results from a number of site page load tools including Google Page Speed so I am wondering if there are any fixes / add-ons that can solve the issues.

Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 586.9KiB (75% reduction). These images are primarily from the slide show and template images on the page (Cart, menu, pagination next/previous etc) - can these be handled by IH4 or is there something else to do it?

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 5 blocking script resources and 11 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.
Remove render-blocking JavaScript:
…l_business/jscript/jscript_flexslider.js
https://ajax.googleapis.com/ajax/lib.../jquery.min.js
...business/jscript/css_browser_selector.js
…_all_business/jscript/back_to_top.min.js
…esponsive_all_business/jscript/script.js


Optimize CSS Delivery of the following:

…ve_all_business/css/style_imagehover.css
…sponsive_all_business/css/stylesheet.css
…_business/css/stylesheet_back_to_top.css
…ss/stylesheet_betterCategoriesEzInfo.css
…_business/css/stylesheet_css_buttons.css
…_business/css/stylesheet_footer_menu.css
…_business/css/stylesheet_middleboxes.css
…_business/css/stylesheet_module_tabs.css
…e_all_business/css/stylesheet_slides.css
…sponsive_all_business/css/index_home.css
…sponsive_all_business/css/responsive.css

any assistance will be appreciated
cheers,
Mike
