Get Scalability Pro →Comparing W3 Total Cache with Scalability Pro? This page breaks down the key differences and similarities so you can find the best fit for your WordPress or WooCommerce store.
Overview of W3 Total Cache
W3 Total Cache improves the SEO, Core Web Vitals, and overall user experience of your site by increasing website performance and reducing load times via features like content delivery network integration and browser caching.
How Scalability Pro differs from W3 Total Cache
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 W3 Total Cache and Scalability Pro?
Scale is where most plugins start to struggle, and exactly where Scalability Pro was designed to thrive. Unlike W3 Total Cache, every Scalability Pro release is stress-tested against a one-million-product WooCommerce store before it reaches your server. If your load times have been creeping upwards as your catalogue grows, migration is simpler than you might fear — and a free trial means you can confirm the improvement on staging before making any commitment.
What do others say about Scalability Pro?
My client site has about 10k products variations. Page loading time was around 10s, and by adding this plugin and doing a quick setup by following the guide, the WooCommerce pages now load in 2s. Still a bit more tweaking to do on my side with a few different options, but this plugin took my client site from being useless (yes a 10s load time for product pages renders your site useless!) to very useful 😉 Thanks for the great plugin and support!
Works very well, noticeable results immediately.
This plugin is brilliant!!! Would give it 10 stars if I could. Brought the site loading times down to less than 2 seconds – was sitting at about 10 seconds before. Had a few problems with the configuration but the support was great and got me setup in no time. I highly recommend this plugin.
