We're sponsoring an online event for one of our clients, and have allocated 1.5GB to their project.
They're running a WordPress installation that gets a good number of hits/views, however in a couple weeks they're going to get hit real hard with traffic as the actually 'event' starts. (A entrepreneurship summit with a handful of speakers being streamed live).
Currently the setup is rather basic, cPanel+Apache+WordPress
Since we're sponsoring this and are a advertised partner of this event it's in our best interest to have everything optimized for best performance as visitors of the site will clearly see that we are hosting/sponsoring the website.
So, for a WordPress installation that gets a lot of traffic what would you recommend would be optimal in terms of server setup? The goal is to serve pages as fast as possible, but while also being able to serve a large number of concurrent connections on the days the event itself is taking place.
I have little experience with WordPress to be honest, even less configuring a server specifically for a single WordPress install. Monitoring the server with Munin so i'll be able to take note of any changes to see if it works or not. I do not have access to the WordPress Dashboard, so I will ask the owner what plugins he has installed (As I know someone here will ask) to see which ones can be disabled.
