Varnish For Xenforo 2.3.13.0.0

Stop rebuilding the same page a thousand times a day.

Every visitor triggers the same work: templates rendered, queries run, forum logic executed — all over again, for a page that hasn't changed. At 300ms per build it feels fine. At 300 visitors at once, it doesn't: pages crawl, CPU pins, and the obvious "fix" is a bigger server bill.

You don't need a bigger server. You need to stop doing the same work twice.

Varnish for XenForo keeps finished pages ready and hands them straight to visitors.

• Milliseconds, not milliseconds-plus-PHP. The page is already built. Varnish serves it before your forum software even wakes up. Visitors stop waiting; your CPU stops sweating.
• Fresh content, instantly. A new reply, an edited resource, a moderation action — the cache is purged the moment it happens. No stale pages, no "wait for the refresh window."
• Traffic spikes cost you nothing. The same server that struggled at 300 concurrent visitors now handles several times that, because it's no longer rebuilding identical pages. Delay your next upgrade by months — or skip it.
• Your members never notice a difference. Logged-in users bypass the cache entirely. Posting, replying, searching, private messages, the "who's online" counter — all behave exactly as before.

What that's actually worth

• Search visibility. Page speed is a Core Web Vitals signal. Faster pages help you rank better on the queries you already target — free traffic you're currently leaving on the table.
• More pages per visit. Every 100ms of delay costs you engagement. Instant pages mean visitors click deeper instead of bouncing.
• A smaller hosting bill. The cheapest server upgrade is the one you never buy.

Common questions, answered up front

• Will visitors see old content? No. Cache is purged on every write.
• Will it break my add-ons or theme? No. Nothing in the forum logic changes — only how finished pages are delivered.
• Can I undo it? Yes. Turn it off and your forum runs exactly as it did before, just slower.
