Speed audit for centriym.com
Measured PageSpeed for this page as it stands today. The WebSpeed run loaded different content, so there is no fair comparison to put beside it.
Speed Index from a single check. Repeat checks of the same page typically differ by around 30%, so read the two times as a direction, not a precise multiplier.
Your page as PageSpeed’s mobile test saw it when loading finished — the original, without WebSpeed Fast.
During this check the WebSpeed version didn’t load the same content as your current page, so the two scores describe different pages. A higher number here says nothing about speed, and we don’t present it as a result. Leave your contact and this page goes to our team: we’ll find out why the content differed and measure again. If a fair comparison shows a speed-up, we’ll write to you.

| Cumulative Layout Shift. A score for how much visible content unexpectedly jumps around while the page loads — one of Google's three Core Web Vitals.≤ 0.1 | 0 | 0 | No change beyond run-to-run noise. |

What holds the main thread
Lighthouse attribution, lab run| Time a script kept the browser busy beyond 50 ms per task — the same pieces Lighthouse adds up into Total Blocking Time. While it lasts, taps and clicks wait. Counted on the recorded run, so the total can differ from the simulated TBT above. | Now | Fast |
|---|---|---|
| Google CDNThird-party service · CDN | 1,376 ms | 0 ms |
| google.comThird-party service | 168 ms | 0 ms |
| Facebook Pixel, the ad-tracking script. While the page loads it sets itself up and reads the page, and the browser cannot react to taps meanwhile. Fast does not remove it: tracking keeps working.Third-party service · Social | 91 ms | 73 ms |
| The site’s own scripts, plugins and services not listed above (each under 50 ms or past the top three), and browser work Lighthouse could not tie to any script.Site’s own code, smaller scripts, unattributed | 77 ms | 49 ms |
Fast removes nothing: every script still loads and runs, and Fast starts what it safely can after the page is ready to use.
Each number comes from one lab run. A script that ran after the run ended shows 0 ms.
