Scalability Pro is our core WordPress optimisation plugin. As we complete performance analysis jobs for clients, we add optimisations for various themes and third-party plugins into Scalability Pro. The only thing we can’t optimise inside Scalability Pro is search and filters, which is why we made Super Speedy Search and Super Speedy Filters to complement Scalability Pro.

  • Future proof your website – a scalable site will not slow down as your site gets bigger
  • Reduce server cost – Scalability Pro speeds up many slow SQL queries that run through WP_Query, for example, the main query on your archive pages (shop or posts or custom post types)
  • Easy to use – includes one-click custom indexes, automatic front-end query rewrites and options to disable unused wp-admin features to speed up your back-end
  • Save time – includes optimisations to speed up imports and exports
  • Includes optimisations to speed up slow themes, e.g. Avada and speed boosts discovered through our Performance Analysis Service
  • Good for Googlebot, admins and users – Speed up imports, archives, wp-admin, XML sitemaps and slow themes
  • Never worry about performance or scalability again – purchase includes access to our Discord Server so you can chat directly to Dave Hilditch about your site performance
