ShortPixel Adaptive Images vs Scalability Pro

Well. Very long story in short format. I set up site for my client. All products are imported via XML / JSON from different wholesale warehouses. At the moment 26k total products / 18k in stock. With over 10k products and with Divi theme site started to slow down. Divi itself is quite heavy at these level because of per post / taxonomy templates and generating static assets per post / tax. Even if these Divi side optimizations are turned off, site is quite slow. So we started testing. Keep in mind – we had frontend assets optimized so LCP / FCP etc metrics were on par with that kind of structure. Biggest problem was on backend. For Google / GTMetrix it meant TBT (total blocking time) or as I understand – time for server to return data – that was around 12 seconds. Turned off Divi "performance" we got it 3 seconds down but still over 8 seconds. So, here comes Scalabilty Pro. At first it was like – meh, i get it down to 3 seconds. Store became usable. More or less. But after wee bit tweaking and testing, combining with Perfmatters and WP Rocket – at the moment we sit TBT 10ms dektop / 10-700ms mobile. And we can use page preloading again which previously clogged down DB. So, SSP only with indexes did a miracle on a site. With other tweaks admin pages are usable and site mostly works faster than small static pages. And this all runs on shared web hosting at zone.ee server. In another hand – Dave is awesome. Very fast support on Discord – explain problem and soon you have a solution.

Dave made it right, we had express speed up in admin area. I almost gave up with woocommerce, but after this speed up we can definitely work smoothly. Thanks Dave

Recommend Scalability Pro if you have a lot of products and use wpallimport or wpallexport, improve import and export and also speed up your website.
