How Scalability Pro differs from WP-Optimize
All plugins from Super Speedy Plugins share a SQL-first architecture and an uncompromising focus on performance — and Scalability Pro is no different. Here is what sets it apart:
Upgrade your WordPress engine with Scalability Pro.
Lifts the limits on how big your WordPress website can be by adding key indexes to speed up slow queries, rewriting queries to be faster, and providing toggle-on-off functionality for WP stuff you don’t need which is slowing down your site.
How to choose between WP-Optimize and Scalability Pro?
Choosing between WP-Optimize and Scalability Pro comes down to how seriously performance at scale matters to your business. Scalability Pro was built from the ground up with a SQL-first architecture, and every release is benchmarked against a one-million-product WooCommerce store before it ships — the kind of rigorous testing that surfaces the performance issues other plugins quietly ignore. A free trial is available so you can see the difference on your own staging environment before committing.
What do others say about Scalability Pro?
Super happy with Scalability Pro, the support, and the results – sped up my imports by multiples. I first came across Dave and his work speeding up large Wordpress/WooCommerce sites by watching his Wordcamp presentation on scaling Woocommerce – before he had this official plugin. Having all of that expertise distilled into a plugin, it's pretty amazing and the results speak for themselves. A+++++
The plugin improved category loading and page display from over 15 seconds to 2 seconds instantly. Over 250,000 products on WooCommerce. The other pages are the same, this can be seen immediately, especially when there are more products on the page
Our current WP websites have been really laggy and despite switching to more powerful servers, we kept encountering bottlenecks until we found WPI. We are currently using Super Speedy Search + Scalability Pro and it has been phenomenal with the performance improvements! Across 2 of our websites on 1 server, we are looking at 90k MAU with 6k products total. Dave has also been a great help with any bugs during the setup process – really speedy response and he sure knows what he is doing!
