We all want (and need our e-commerce site to run fast and look good). Recently, with a client who has over 30,000 products in their catalog, I found that category pages were taking 10-13 seconds to load. Magento was slowing to a crawl. Looking further, I found that when turning off Configurable Swatches in the backend, the pages load at around 1 second.
For this client, we only wanted the swatches to load on the product pages anyway (where it doesn’t seem to impact performance as much).
