Can you help me figure out the issue of data caching?

Question

PHP

The page takes a long time to load. The reason is that I request a huge amount of data from the database and then process it with a php function.
Where do I begin? I started to study HTTP caching, I can’t figure out how it works. Is the browser caching the page? But for me, as the page was loaded for 8 seconds, it is also loaded after enabling http caching. What am I doing wrong? Thank you.

Answer 1

Memcache you need either redis or regular file caching.
