On my front page (index.php) I do 2 queries that can pull quite a bit of data.
I am concerned that it is too resource intensive. What I would like my system to do is to update the page itself say every 5 mins and display that data - rather than rerunning the two queries every time someone lands on the page.
I believe hat this is called “caching” but I am unsure exactly what it is and how to do it.
If someone could name my problem more accurately and suggest an approach with some tools - I should be able to figure out the particulars.
I am right now a little unsure what and how to do this - or even if I should.
