Your site feels slower to you than to your visitors?
You're never served a cached page while logged in. That's how page cache works, so your own pageviews drag a real-user average down.
xSpeed leaves logged-in users out by default:

Site behind a CDN and first byte isn't quick?
css-tricks.com today: we measured 240ms to first byte. Google measured the server answering in 5ms.
@Cloudflare returned cf-cache-status: DYNAMIC. The edge forwarded every request. The gap is distance, not the server.

Purged the cache and the page is still old?
A @Cloudflare Free zone allows five purge requests a minute. Purge on every post save, comment and stock change and the bucket empties — dropped requests fail quietly.
Let the plugin purge the CDN:

Worried xSpeed's AI features watch your visitors?
Only SmartPredict records visitor data. Adaptive Cache and Smart Image read aggregated site data and never see a visitor.
The consent gate is on by default, and holds before Pro is installed:

Priced per pageview? You pay for the tier your biggest month needs, all year.
Five sites we run, sized for their peak: $468.00 metered, $299.75 on five fixed licences.
Two of them stay under 7,000 pageviews a year and still pay $84.00 each.

Nothing on your WordPress page says how long to keep your CSS.
@WordPress core sends Cache-Control in two cases: a logged-in visitor, and the 10-minute comment window. Otherwise none. RFC 9111 lets the browser guess 10%.

Caching made your first byte much faster and your Lighthouse score did not move?
Across 958 sites we scanned, caching cut median TTFB 73% and left LCP where it was. Paint is decided by images, fonts and blocking files.

Your theme lazy-loads the hero image, the one image LCP measures.
xSpeed Cache preloads the biggest above-the-fold image instead, overriding it. Free tier, on by default.
Picked a tracking pixel? Exclude that one, don't turn preload off:

Your lab test passes the layout-shift check. Google's real-user data can still fail it.
nobelprize.org today: the lab measured CLS 0.003, well inside the 0.1 limit. Real visitors on desktop measured 0.45.
Load and response times were both fine. Shift was not.

WP Rocket's pricing page says $5. Older comparisons say $59.95. Both are right.
Re-read 6 Nov: every card now prints a per-month price and bills a year. The checkout still adds the $59.95 yearly product.

You schedule a post for 6am. The first reader pays to build the page.
xSpeed Pro can fetch a scheduled post the instant it goes live, so that visitor gets a cache HIT instead.
Scheduled prewarming is off by default. One switch:

Lighthouse 100/100 does not mean every delivery check passes.

Static-asset cache policy still scores 50%: 6 of the 8 files are on another host.

Your cache says 95% hit rate. On how much of your traffic?
Across sixteen WordPress sites we run, 90,550 requests, 37.7% of the day, sat outside the ratio: checkouts, logged-in sessions, feeds, 404s.

Told which caching plugin is "most popular"?
Three instruments, one question, three different winners: 7,000,000+ installs, 354,098 origins, and our own archive, which crowns our plugin and is wrong.
Ask "out of how many":

Headings blank for a second while your font loads?
xSpeed puts font-display: swap on your Google Fonts URLs by default, and rewrites a blocking auto or block to swap.
Preload is the trap: above-the-fold faces only, one or two.

Every guide warns: don't lazy-load your hero image.
Across 2,083 WordPress homepages, only 8.3% do.
21.3% send two or more fetchpriority=high instead. Core sends one; the extras cancel it.
Count yours. It should be 1:
