The website is very slow. Optimization needs to be done.

Good day, I have familiarized myself with the website, I can conduct an audit, find all the shortcomings and non-compliance with Web Vitals standards, and then I can perform full optimization according to Core Web Vitals standards (without using modules, only manual code optimization).

Good day!

I have preliminarily checked your website and already see the first bottlenecks: the homepage responds slowly, there is a JS file loading ~30+ ms (likely a blocking script), and some images need optimization. I will show the exact root cause after a deep audit — for this, I need access to FTP, the hosting panel, and the OpenCart admin area.

What I will do:

- Performance audit: server (PHP/FPM, MySQL, cache), modules/ocMod, template, events/hooks, queues, error logs, and slow queries.

- Elimination of causes:
… – optimization of SQL and indexes, query cache;
– updating/configuring PHP-FPM/OPcache;
– resolving module/ocMod conflicts;
– critical CSS + defer/async for JS, removal of blocking scripts;
– image optimization (WebP, correct sizes, lazyload);
– configuration of page/object cache;
– CDN (if desired).

- Control metrics: TTFB, LCP, CLS, FID; I will achieve goals for the homepage (LCP ≤ 2.5 s, TTFB ≤ 0.8 s on your hosting).

Report: what exactly was slowing down, what has been fixed, how to prevent recurrence.

Deadline:
1–2 days for a full audit and quick fixes; 2–3 days for implementing deep changes (if heavy module conflicts are found).

Ready to start today. Please send the access (FTP, hosting, admin) and briefly: OpenCart version, theme, list of installed modules.

Hello. You are posing the question in such a way that it is unclear how to convince you of what the root cause is. It is also unclear how you define what is slowing down? What kind of magnitude is this? Feel free to reach out. I will optimize the database correctly for you. This is something that must be done.
