Databases & SQLDiagnosed server load, over 12 million database queries per day, which led to 20 minutes of CPU time and over 8 million SELECT/UPDATE/other type queries.

Bring the website indicators into the green zone of PageSpeed Insights.
Web ProgrammingAs part of this project, a comprehensive speed optimization of the website was carried out to bring its metrics into the green zone of Google PageSpeed Insights. The work included a detailed performance analysis, identification of bottlenecks, and their elimination.
The website structure was optimized, unnecessary DOM elements were reduced, and JavaScript and CSS were minimized and deferred, which allowed for faster page rendering. A complete image optimization was also conducted: WebP was implemented, and lazy-load was configured, significantly reducing the page weight.
… In addition, caching mechanisms were improved both at the browser level and on the server, using gzip and brotli for resource compression. For additional acceleration, Cloudflare CDN was connected, which improved content loading speed and overall website performance.
As a result, the website achieved high speed metrics, positively impacting SEO, user experience, and the effectiveness of advertising campaigns.
