Why it matters
Users expect pages to appear instantly — especially catalog and checkout flows.
- Site response up to 100× faster than standard mode
- Better rankings via improved Core Web Vitals
- Higher e-commerce conversion — fewer bounces on slow loads
- Any 1C-Bitrix: Site Management project can run in composite mode
How it works
The complexity stays on our side — you get a faster site without changing your workflows.
Two page layers
HTML, CSS, JS and images as static shell; cart, auth and personalized blocks as dynamic fragments.
New load cycle
Cached shell is served instantly — users read and click while dynamic data is still loading.
Background fetch
Dynamic areas load asynchronously and are cached in the visitor’s browser.
What we deliver
- Speed audit and enabling composite mode
- Template zones marked static vs dynamic
- Cache, CDN and catalog invalidation setup
- Regression check for cart, auth and forms after rollout
Page load dynamics
Load sequence
Static first
Cached layout, catalog and copy — no PHP wait.
Immediate UX
Users scroll and click while dynamic data is still loading.
Dynamic in background
Cart, profile and personal prices arrive in a second request.
Browser cache
Return visits are even faster with client-side fragment cache.
Sites in composite mode show the “Fast with 1C-Bitrix” badge — a sign the technology is active.
