Hey! There is a website kaskad-krovli.ru. After optimizing the images on the main page, it began to give out a page speed of 40, before that it was generally 20. Are there any clear ways to overclock the site?

В ПРИМЕРЫ НАШИХ РАБОТ используйте миниатюры, а не полные изображения, уменьшенные через css. И включите сжатие.

Use phpinfo() to check if the appropriate extensions are loaded, and if possible use caching and compression, you can adjust the values
