[Закрытые] problem speed load website with wpml

Good morning,
We're testing WPML on the test site we'd like to go live soon (скрытая ссылка), and we've noticed that analyzing the site's loading speed and performance using Pagespeed, Pingdom, etc., it seems like the site's loading is slowing down due to the WPML translation. Specifically,
- Images are loading twice for both English and Italian, even though they're the same.
- In general, the site's loading is slow because it loads both English and Italian simultaneously, instead of just once (the second one only loads when switching languages).

Do you have any ideas on how to fix this?

Thanks,
Guido
