My name is Anthony McKenna and I am engineer at Domino's Pizza LLC. My team is working to adapt Moodle to fit our needs for an intranet-based knowledge assessment center for our team members. We're piloting the project now with a limited number of stores and teams.
We're working on estimating the requirements for a production environment. We are using RedHat and MySQL. We have approximately 110,000 users and are anticipating a maximum of 5,000 simultaneous users.
I am finding a wide array of results from different installations with different equipment setups. However, I have not seen very many installations with 100,000+ users. I would like to hear from anyone who has clustered Moodle for a very large number of users and how this system has performed for them.
What setups have worked for you and your large organization?
