Cada função é um interruptor, com as suas próprias exceções.
O Celeris é um conjunto de interruptores independentes. Cada um pode ser testado sem risco, e cada um diz o que muda.
01
The web server answers. WordPress stays asleep.
On an ordinary visit, PHP starts, loads WordPress, queries the database, runs your theme and every active plugin, and builds an HTML page that is identical to the one it built a minute ago. Celeris writes that page to disk once and gives your web server a rule to hand back the file directly.
The practical effect is that your response time stops depending on how much you have installed. A site with thirty plugins and a site with three are served at the same speed, because on a cached page neither one runs.
02
Only the rules the page actually needs.
A theme stylesheet is written for every page of the site at once. Any single page uses a small part of it, and the browser still has to download and parse the whole thing before it can paint anything. Celeris analyses each page in the background, inlines the rules it really uses, and loads the remainder after rendering.
The analysis runs on your own server, from the HTML your site produces: no page is sent anywhere for this. The optional critical CSS service is the one exception, and it says so — it asks our renderer to open the public URL you point it at, and returns the styles for the first screen.
03
Third parties wait until someone is actually there.
Analytics, chat widgets, map embeds and pixels are loaded on every visit, usually before your own content. They compete for the same connection and the same main thread, and they are the single biggest reason a well-built page still feels slow.
Celeris holds them back until the first scroll, tap or key press. A visitor who leaves after two seconds never loads them at all; a visitor who stays gets them a fraction of a second after touching the page, and notices nothing.
04
The lightest format the visitor can read.
Images are usually most of the weight of a page and the easiest thing to fix. Celeris generates WebP and AVIF versions of what is already in your library, keeps the original untouched, and serves whichever one the visiting browser accepts.
It also fixes the two things that make a page jump while it loads: images with no declared dimensions, and images below the fold that download before anyone scrolls to them.
05
Numbers from your site, not from a brochure.
Every optimization plugin promises a result. Celeris times your own pages with the cache off, then with the cache on, and shows you both figures side by side in your dashboard. If a switch changes nothing on your site, you will see that too.
The same screen keeps the history, so a slowdown introduced by a new plugin or a theme update shows up as a line that moved, rather than as a vague feeling that the site got heavier.
06
One save, every layer cleared.
A cached page is only fast if the server is told how to serve it, and only correct if every layer forgets it at the same moment. Celeris writes the Apache and LiteSpeed rules for you, and gives you the Nginx block to paste when PHP runs behind Nginx.
When a post is saved, the purge is relayed outward: the local files, then Varnish if your host runs it, then Cloudflare or whichever CDN you point it at. Only the pages that changed are cleared.
Cada página é analisada em segundo plano: somente os estilos que ela usa ficam na página, o resto carrega sem bloquear a exibição.
Rastreadores, chats e mapas só começam na primeira interação. Todo o resto é adiado para depois da exibição.
Carregamento sob demanda, dimensões ausentes preenchidas, WebP e AVIF gerados e entregues, YouTube e Vimeo substituídos pela miniatura.
Tempo de resposta com e sem o Celeris, notas do PageSpeed antes e depois, direto do seu painel do WordPress.
Regras do Apache escritas para você, bloco do Nginx fornecido, limpeza repassada ao Varnish e à Cloudflare, reescrita para o seu CDN.
