Performance

HTTP/3 and QUIC - what they give a website

HTTP/3 and QUIC improve how connections are established and maintained, especially on mobile and lossy networks.

Technical guides See hosting FAQ

When this matters

Not every synthetic test shows HTTP/3 benefits well. Real traffic, TLS, caching, compression and browser support matter.

What HTTP/3 and QUIC mean on hosting: faster connections, better mobile behavior, TLS and performance test caveats.

Practical checklist

  • enable SSL and correct HTTPS redirects
  • check browser support
  • test with and without cache
  • compare TTFB and resource loading time

How Hostilla.pl helps

Hostilla.pl treats HTTP/3, QUIC, caching and modern hosting technologies as a performance stack, not a single magic feature.

What to prepare before contacting support

If you need support, include the domain, account name, time of the problem, exact error message, recent changes and one example URL or mailbox. This lets support check DNS, SSL, mail logs, PHP, database, backups and application configuration faster.
