Overview of Swift Performance
Swift Performance is a WordPress caching and optimisation plugin offering page caching, asset minification, image optimisation, and database cleanup. It includes a smart cache warming system and a server-side rendering mode for JavaScript-heavy themes, making it a comprehensive front-end performance toolkit.
How Scalability Pro differs from Swift Performance
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.
Swift Performance is a broad optimisation toolkit focused primarily on HTML caching and front-end asset delivery. Scalability Pro takes a different approach, targeting the WooCommerce database queries that slow sites down under load — specifically the SQL patterns that degrade as product count and order volume grow. The two tools address different layers of the performance stack.
How to choose between Swift Performance and Scalability Pro?
If Swift Performance has helped with static page delivery but you still see slowdowns during high traffic or after your catalogue grew, the issue is typically at the database level. Scalability Pro was built specifically for that layer, with a SQL-first architecture validated against one-million-product catalogues. A free trial is available to test on staging.
What do others say about Scalability Pro?
Today put this tool on my website with 50,000+ products. The page loading times were really 10 to 20 seconds during imports via wpallimport. Set all steps and go through and now around 1 to 2. What a great tool 🙂
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
