Get Scalability Pro →Comparing Jetpack Boost 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 Jetpack Boost
Jetpack Boost is a free WordPress performance plugin from Automattic that focuses on Core Web Vitals improvements. It offers Critical CSS generation, deferred JavaScript loading, and lazy image loading. It is designed as an accessible, low-configuration option for site owners who want quick front-end performance gains without manual configuration.
How Scalability Pro differs from Jetpack Boost
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:
Your site was fast when it was small. Now archive pages, imports and wp-admin screens are waiting on the database. Scalability Pro adds the indexes WordPress leaves out, stops it counting rows nobody reads, and defers the work that turns an import into an overnight job.
Jetpack Boost is focused entirely on front-end delivery — Critical CSS, deferred JS, and lazy images. It does not touch the database or address the WooCommerce query patterns that cause high TTFB under load. Scalability Pro operates at the SQL layer, targeting the slow queries that accumulate as your product catalogue and order history grow.
How to choose between Jetpack Boost and Scalability Pro?
Jetpack Boost can make a visible improvement to Lighthouse scores, but if your site slows under real traffic or as your catalogue grows, the problem is in the database rather than the front end. Scalability Pro targets those SQL bottlenecks directly and is benchmarked against one-million-product WooCommerce stores. A free trial lets you validate the improvement on staging.
What do others say about Scalability Pro?
This plugin made the websites for my clients quite faster, something other "speed" plugins couldn't do. If you need one "speed" plugin, it's this one! You only need to keep in mind that to achieve this, you switch off some calculations and some options you might need. So you have to read carefully the description of what the option does.
I ordered the WPI Performance Plugin and I´m absolutly impressed. I never thought that I can get that speed on my site. I´m planing to build more sites and shure I will buy the WPI Performance Plugin for that sites too.
I have a site with many products and heard about Scalability Pro and after installing this plugin my site got blazing fast. I recommend this anytime for everybody who want fast woocommerce site. Thanks to Dave for support.

What's new in Scalability Pro?
6.38.0 (30th October 2026)
- *Alter main query to use EXISTS rather than LEFT JOIN* leaves pages Super Speedy Filters serves from its own index to Super Speedy Filters, so they no longer carry an extra product visibility check.
6.37.11 (30th October 2026)
- Fixed database errors about missing `scalability_pro_post_count_cache` and `scalability_pro_transient_cache` tables after activating Scalability Pro with WP-CLI: activation creates the cache tables before anything uses them.
6.37.10 (29th October 2026)
- Updated super-speedy-settings to 1.14.3: update downloads now send the licence key in a request header instead of the download URL.
6.37.9 (29th October 2026)
- Fixed native WordPress search running slower with Scalability Pro's indexes installed on large stores: the `wpi_scalability_pro_sitemaps` index now leads with `post_type` and is rebuilt automatically after updating.
6.37.8 (29th October 2026)
- Reworded the *Alter main query to use EXISTS rather than LEFT JOIN* description: it changes how the SQL is written, never which products are shown.
