Scalability Pro v4.62 Scalability Pro helps you identify and fix potential and existing scalability issues with your site. Scalability is not quite the same as performance – it’s related to how well you can keep your site performing fast as your site gets larger. A highly scalable site will not slow down as your site gets bigger. The Scalability Pro Plugin is the core WP Intense plugin to transform the speed and scalability of your WordPress site.

Change Log

4.62 (30th September 2020)

  • Added new WPI Settings page where users can enter their license key to enable plugin updates

4.61 (22nd June 2020)

  • Added multisite compatibility

4.60 Beta (1st May 2020)

  • Prevent query alterations for cron and ajax where the order of results may actually matter for functionality
  • Improved removal of GROUP BY when group by not needed – gives speed boost in some cases

4.59 Beta (16th April 2020)

  • Changed mechanism for the ‘WHERE NOT EXISTS’ option to make it work with all taxonomies and multiple taxonomies (previously was disabled and when enabled it only handled 1 taxonomy) – this optimisation helps in many cases but not all – you’ll need to test it to check with your data config

4.58 (31st March 2020)

  • Added new index on wp_posts on just the guid column. Some themes grab posts directly using SQL against wp_posts and just use the guid. Typically this is when they’re grabbing images. They shouldn’t do it that way but some do.

4.57 (27th August 2019)

  • Fixed bug related to ‘removing woocommerce ajax variations count’ which improves performance of pages with many variations
    • bug was related to items which didn’t have all variations created. Fix was to return at least 1 of the variations which seems to fix the Woo JS code so that it will correctly use Ajax to fetch prices.

4.56 (16th May 2019)

  • Updated code to prevent ‘sort order suppression’ and ‘pagination suppression’ from running on admin pages

4.55 (16th May 2019)

  • Re-added experimental EXISTS option for those users who have already set it and are successfully using it. Full fix coming soon to re-add it to options page.

4.54 (8th May 2019)

  • Further hotfix for sitemap index

4.53 (8th May 2019)

  • Fixed sitemap index in cases where somehow the keys were > 1000 characters

4.52 (8th May 2019)

4.51 (6th May 2019)

  • Altered the plugin update checker to use the latest version and avoid warning message.

4.50 (12th April 2019)

  • WHERE EXISTS experimental option now fixed – if all 3 wp_query options set, dogs category on foundthru is 0.0009s

4.49 (1st April 2019)

  • Swapped out use of dbDelta to use generic CREATE statement instead since it seems there is a bug inside WordPress core –
  • Removed the .js file from front-end as it’s not yet needed

4.48 (28th March 2019)

  • Bumped version number to help customer

4.47 (28th March 2019)

  • Removed row-level caching from WooCommerce->Orders (needs bugs fixed)

4.46 (4th March 2019)

4.37 (11th January 2018)

  • Improved product listing page speed

4.36 (11th January 2018)
