Estoy teniendo problemas de performace en mi sitio y soy nueva en esto alguien sabe cuales son parámetros óptimos para un buen performance?

Witam serdecznie, Prowadzę sklep na silniku Presta 1.6.1.24 i od pewnego czasu analizuję serwis za pomocą zewnętrznego narzędzia https://gtmetrix.com/. Zależy mi, żeby wypracować najwyższy możliwy scoring. Natomiast w sieci nie widzę nigdzie informacji jak można poprawić poniższy element: Jedyne informacje do których na chwilę obecną dotarłem to modyfikacja pliku .htaccess natomiast bez szczegółów dotyczących elementu z powyższego screenu. Czy ktoś ma na to rozwiązanie ? Z góry dziękuję. Oczywiście w razie pytań, proszę śmiało pisać.

Hallo there, we have Prestashop 1.7 on our fresh new CentOS 7 VPS server. The Configuration is 4 v CPU, 8 GB RAM and 160 GB SSD. PHP 7 and 10.1.43-MariaDB. We have about 160k products in cca 200 Categories. Some category pages are very very slow (20sec). Website URL is www.moto1.cz, HomePage loads Ok, Product page too, but some category pages are very slow, for example https://www.moto1.cz/424-plasty-polepy. Does anybody know how to speed up the process? Very thank you all.

An important factor not reported by browser performance tools and something that not only affects your SEO (as it concerns performance) but more importantly your customers shopping experience Using HTTPS without Keep-Alive Connections. it's up to four times slower than your http connection when not using keep-alive.

I'm trying to squeeze out a little more speed of my PrestaShop site. I have tried running Apache2 with fastcgi/php-fpm instead of mod-php, and I have tried installing and enabling APC. Using _PS_DEBUG_PROFILING_, I cannot see any substantial increase of performance, which surprises me. I have verified with phpinfo() that it is in fact running with the expected modules. Have anyone noticed any improvement of performance tweaking this setup/parameters?

Hi I've merged all Prestashop 1.4 stylesheets that my store uses into a single 16K file - it's a very minimalist design. Having done this I was wondering if the various php files in the modules folder (and elsewhere) that have references to css files that no longer exist presents a problem for the PS backend? Is it okay to leave things like: "Tools::addCSS(($this->_path).'blockcart.css', 'all');" lying around in various files that point to non-existent files? Or should I somehow get rid of them? Thanks for any advice.
