The speed of Prestashop is bad. For example, analysis via Google PageSpeed is a disaster especially for the mobile version.

[Cricchio]

yes that's true, but the ttfb is really high. I tried another site on the same server and it doesn't have this performance.
Category pages are the slowest. I also decreased the number of products per page, but nothing

leave profiler debug

Thinking of pagespeed the actual version of prestashop is not very fast.
Desktop is not very good. But mobile is a totally performance desaster.
You need a lot of work to get good speed results.

I think this should be one of the most important things to work on the next version of PrestaShop.

[Cricchio]

@waschier-design I agree with you.
