Overview of LiteSpeed Cache
LiteSpeed Cache for WordPress is an all-in-one site acceleration plugin featuring an exclusive server-level cache and a collection of optimization features, including image optimization, object caching, and database cleanup.
How Scalability Pro differs from LiteSpeed 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:
Your WooCommerce shop page went from over 180 seconds to 0.4 seconds – on 820,000 products. Scalability Pro is the performance plugin for WordPress and WooCommerce sites that have grown too big for their own good. It adds the right database indexes, rewrites your slow queries to use them, and switches off the features that quietly grind to a halt once you pass 5,000 products, orders or users.
- Makes WP_Query fast and keeps it fast as your catalogue grows
- Speeds up archives, wp-admin, imports, exports and XML sitemaps
- Typically around a 10x boost on large imports, with lower CPU while they run
- A toolbox of optimisations you toggle on and off, no code required
- Complements your cache – it fixes the queries caching cannot

How to choose between LiteSpeed Cache and Scalability Pro?
Scale is where most plugins start to struggle, and exactly where Scalability Pro was designed to thrive. Unlike LiteSpeed 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?
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!
Great plugin and great support thank you

What's new in Scalability Pro?
6.23 (20th May 2026)
- Added a "Recheck Licenses" button above the licence table on the Super Speedy Settings page so customers have a clear way to refresh licence status after a renewal or upgrade without scrolling down to the licence-key field. The button is disabled until a licence key is entered/saved and re-enables as you type.
- The Recheck flow now also force-bypasses the auth-server's own 1-hour licence cache (via a `force=1` flag on the `wpiapi/check_product_key` call), so renewals/upgrades that completed less than an hour before a recheck no longer show as expired/exceeded. Normal admin page loads continue to use both caches as before — only an explicit Recheck click bypasses them. (Lives in the `super-speedy-settings` submodule, so the change propagates to every Super Speedy plugin.)
6.22 (13th May 2026)
- Security: added capability checks and nonces to every admin AJAX endpoint that was previously reachable by low-privilege or unauthenticated users (slow query log fetch, index create/drop/drop-all, symlink create/delete, wp-config rewrite, slow query log truncate, term recount, profiling results save, cache clears, settings export/import, CSV export, action scheduler maintenance, and the WP All Import diagnostic helper)
- Security: removed `wp_ajax_nopriv_*` registrations from the slow query log fetch and the post-count / author-count cache clear endpoints — these were admin-only operations that should never have been exposed to unauthenticated visitors
- Security: escaped every column rendered in the Slow Query Log admin table (`time`, `url`, `query`, `stacktrace`, `duration`) — prevents stored XSS via a poisoned slow-query log entry being executed when an admin views the tab
- Security: fixed the "Create symlink" button, which previously created a dangling `wp-content/db.php` (the source path the button used had never existed in the plugin) and would have fatal-ed the site on the next request; the slow-query drop-in (`db.php` + `profiling-queries.php`) has been moved into `tabs/slow-query-log/wp-content/` to match the path the button always expected, every readlink check across the tab now derives the path from `plugin_dir_path(__FILE__)` so it works regardless of the plugin's installed folder name, and the symlink source is validated with `is_file()`/`realpath()` before linking
- Refactored: the slow-query-log drop-in files now live under `tabs/slow-query-log/wp-content/` so the tab is self-contained ahead of the planned split of each tab into a separate add-on plugin
- Security: hardened `spro_search_terms` (product attribute search) — requires `edit_products` and null-checks the taxonomy so PHP 8 no longer fatals on an unknown taxonomy
