What are the ways to speed up parsing?

Question

PHP

I would like to know how you can reduce the parsing time? 25,000 products = 25,000 pages. It takes about 4 hours to open the page and collect information.

Answer 1

curl cannot be accelerated, only if multi is used, and yes, run several scripts in parallel

Answer 2

Split into steps, perform steps in parallel, use multicurl and a wide communication channel - to minimize request-response delays.

Answer 3

abandon PHP and rewrite everything in a language that supports multithreading
