Hello to all! Got a question. On my site almost everything is cached. Cached: last comment, last forum, news, etc .. I cache in this way. The script makes the request once every 5 minutes and writes the request to the definition file. The essence of the question: Does it make sense to cache? How much less load or faster download speed. Maybe there is a tiny difference and easier to do through sql?
The sum of the size of the request is 8-10 kb. Online every day increases, but certainly not a geometric progression. Now online at day 200.
