What does max_connections really mean?

Question

I'm trying to set the ideal performance setup for MySQL and resources needed on a shared hosting. My question is, what does max_connections really mean? Is it the number of unique concurrent requests made to the server? So if there are two users, 1 with 1 tab open and the other with 4 tabs open... and both press all their tabs to reload at the same time, will there be 5 connections made to the MySQL DB? Consequently, if we bump this scenario to: 10 people with 2 tabs and 31 people with one tab all pressing refresh at the same time... with our max_connections at 50, will everyone get locked out? The reason I ask is because I want to shoot for low max_connections to be conservative with memory resources since I consistently see the site going into cpu throttling mode Thank you for your help JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

Yes, there is a separate connection opened for each page. However, assuming you're not doing anything database-intensive, the connection will be short-lived and close itself once the page has been served to the client. If you do exceed the maximum number of connections, any subsequent connection attempt will fail.
