Should I cache?

Hi everyone! Got a question. Almost everything on my site is cached. Cached: last comment, last. forum, news, etc. I cache this way. The script makes a request every 5 minutes and writes the request to the definitions file. Essence of the question: Does it make sense to cache? How much less load or faster download speed. Maybe there is a meager difference and it’s easier to do it through sql?

The sum of the request size is 8-10 kb. Online is increasing every day, but certainly not exponentially. Now online at 200 a day.

Answer 1

The cache is only good for displaying large information that is not updated very often, for everything is relative, the difference in speed and performance is not significant. Thank you for your comments.
