When I count the number of apache2 processes, I get about 151, but when I check the number of connections, I get about 208 connections. I want to know if there is any relation between these two. Also, isn't 151 processes low? We have 32GB of RAM with 10 cores. We want to have a support for about 1000 users online, refreshing web pages at specific times. It is actually online exams on our Moodle web site.
