Can you guys tell me why my website is soooo slow?
As you said, there are a few huge images that aren't optimized. You can use tools like Google Lightouse or Koalati to detect potential issues and find things that can be improved.

Watching your Core Web Vitals on Jamstack
Lighthouse tests are a helpful method to measure your web vitals — you can run Lighthouse tests from Chrome DevTools, via the Lighthouse Chrome Extension, or in the command line:

Building an offline-first application with Node.js and SQLite
Now let's check if we properly set up our PWA using a Google Lighthouse check. Right-click on your browser and select "inspect." On the inspect tabs, select lighthouse and click on generate report. If everything went well with your application, you should see an output like the one in the screenshot below:

Show HN: Datagridxl2.js – No-nonsense fast Excel-like data table library
Lighthouse [1][2] Accessibility audit/ scores can be a good tool to check A11Y issues automatically, and it is fairly easy to integrate into your CI/CD Pipelines to get the report automatically to check for issues/ regression.
The web accessibility world is complex enough that simulating different methods of access like using screen readers or different font-sizes and doing manual tests for compliance is not particularly feasible if you want to make your content accessible to all.

How I massively improved my website performance by using the right tool for the job
Performance was compared between the Next.js site and Eleventy site using three free tools: Google Lighthouse, web.dev/measure and Web Page Test. Lighthouse tests were run in Brave Browser dev tools, Web Page Test runs were conducted via the web app using the London, UK - EC2 server, and web.dev tests were conducted in the browser. Given that I advocate for mobile-first development — and that's where performance is most likely to be impacted given the unpredictable speed of mobile data — all tests were conducted in an emulated mobile environment using a medium 3G network speed, on iPhone 6/7/8.

You’re probably using Lighthouse wrong: How we got tricked by a single magic number
You can have more consistent results if you set up Lighthouse CI in an external environment to test your page or use tools like SpeedCurve, but if you need to quickly inspect a website, I suggest taking a look at Page Speed Insights.

10 Tools to measure Core Web Vitals
Lab data on demand and unattended. This version of Lighthouse is oriented to be integrated in a continuous integration workflow to check your metrics before deploying to production. However, you could also use it as command executed in a cron to check an environment performance over the time. I use the latter to check production performance each 12 hours, since there are third parties adding and removing dynamic content that could affect UX. Check its repo here

Continuous performance checks in Nuxt.js with Lighthouse CI and Github Actions
This approach would suit most of the cases however to achieve more accurate performance audits you should be conducting Lighthouse tests on a dedicated server to avoid results being affected by the machine capabilities. In other words, if you are running Lighthouse audits on a repository where there are several pull requests/workflows/pushes going on, the result of this audit may not be accurate and this is what we want to avoid. For that you would need a separate machine with Lighthouse Server installed on it. So on a pull request you would trigger this machine to conduct a performance audit and return response to your repository.
