Get Scalability Pro →Comparing WP-Optimize 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 WP-Optimize
WP-Optimize is WordPress's most popular all-in-one cleanup and performance plugin. It cleans your database, compresses images, and caches your site — all from a single plugin.
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:
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.
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!

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.
