What is the best way to speed up a website?

Question

Web development

Good afternoon!
What would you recommend to speed up the site anis-realty.ru
Can I use cdn?
Who used what and how did you speed up the download?

Answer 1

GTMetrix for example, to help you.
Open the Nginx config - and let's go through the list. You need to decide: caching issues, minification of css / js, image compression if possible, reduction in the number of http hits, etc.
A CDN can and can be, but a last resort if the previous steps don't work enough.

Answer 2

On GET (reading data) - give a full rendering of pages from the server cache.
IMPORTANT! : static page should be assembled from separate cached segments via concatenation/replacement of HTML code (or template HTML code).
On POST (data modification) - update the cache of the desired segment.
Static content with automatic cache control is tricky, but it works really fast!

Answer 3

I think it's still worth playing with the optimization of queries to the database and the side of their processing. faced situations when 2 MySQL queries and reduction of the received data in PHP turned out to be 1.5-2 times more efficient than 1 MySQL query using UNION.
