Overview

Swift Performance is an advanced WordPress caching and optimisation plugin that combines page caching, critical CSS generation, unused CSS removal, and server-level integration in a single package. It offers both a free version (Swift Performance Lite) and a premium version with AI-powered cache configuration. Swift Performance is notable for its strong compatibility with dynamic WordPress sites including membership sites and WooCommerce stores, where standard caching plugins often struggle with logged-in users and cart pages. Its database optimisation module and AJAX request handling make it a strong option for complex WordPress installations.

Key features

  • AI-powered automatic cache configuration (Pro)
  • Unused CSS removal per page type
  • Critical CSS generation for Core Web Vitals
  • Correct caching for logged-in users and WooCommerce cart
  • Database optimisation and query reduction
  • AJAX request batching to reduce server round trips

Common use cases

  • B2B WordPress site with member-only content that must not be incorrectly cached
  • Complex WooCommerce-powered B2B product catalogue needing per-user caching rules
  • Sites with heavy AJAX usage needing request batching optimisation

Why it matters for B2B

B2B companies running WordPress sites with gated content, member portals, or WooCommerce product catalogues need a caching plugin that correctly handles logged-in user states and dynamic cart data. Swift Performance's granular cache exclusion rules and AJAX optimisation ensure that personalised content is not accidentally cached and served to the wrong users — critical for B2B sites where prospect-specific pricing or member-only content must remain accurate.
