I have big problem to solve before we start our website: SPEED OF MAGENTO
Main problem is TTFB(Time To First Byte), and I find connection between problem and product images in Magento.
For example this is loading speed with and without images in product category:
With: https://i.stack.imgur.com/3f3Pn.jpg
Without: https://i.stack.imgur.com/UNnHf.jpg
My current image code is this:
<img class="main-image" src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(219,219) ?>" alt="<?php echo $this->htmlEscape($_product->getName()) ?>"/>
How to change it and try to resolve my problem?
