Turbocharge your ESI performance with Parallel ESI
ESI (Edge Side Includes) is a popular way of composing web pages that requires dynamic presentation of personalized content from different “includes”. It’s what enables companies to tailor highly personalized experiences for end-users in the form of targeted, curated and relevant content and recommendations. If you’re using ESI, as most media and e-commerce companies do, you know that it boosts the flexibility of your dynamic content and is critical to driving user conversions — but you also know it comes with a price in latency.
Parallel ESI features
- Kill latency: With parallel ESI, content delivery is accelerated by up to 75% as it seeks out and fetches needed web page fragments simultaneously.
- Better responsiveness: Because these fetches are done in parallel, responsiveness in ESI-heavy pages is significantly improved.
Parallel ESI benefits
- Up to 75% faster page assembly
- Faster experience for users, especially on mobile
- Seamlessly leverage the power of Parallel ESI, no configuration or code changes are required
