Performance

Performance is the speed layer: it sits in front of your site and serves it faster, without you touching the theme.

What it includes

• DNS — Tuurbo-managed DNS for the domain.
• CDN — global edge distribution of your assets and HTML.
• Cache — edge caching rules with purge control.
• Prerender — pre-rendered HTML for crawlers and answer engines, so JS-heavy pages are still readable.
• Image optimization — modern formats and correct sizing.

Step-by-step activation

1. Add the Performance add-on to your plan (it is billed separately — see Add-ons).
2. Point your DNS to Tuurbo using the records shown in the component. Keep TTL low during the switch.
3. Wait for propagation and the SSL certificate to be issued.
4. Enable the CDN and check that pages still render correctly on desktop and mobile.
5. Configure cache rules: what to cache, for how long, what to always bypass (cart, checkout, account, search).
6. Enable prerendering for the templates that depend on JavaScript.
7. Measure — compare Core Web Vitals before and after in the performance report.

Cache rules that matter

Purging

After a catalogue update or a theme deploy, purge the cache — either the whole site or a specific path. Bulk jobs launched from eCommerce trigger a purge for the pages they changed.

What to expect

Improvements are largest on TTFB and LCP. Layout shift and interaction latency depend on your theme and third-party scripts, so the audit will still flag them if the front-end is the bottleneck.

Rollback

The speed layer is reversible: point your DNS back to the previous provider and your site serves exactly as before.
