I am an administrator for one University, we are using Moodle open-source as LMS by a build at my server. Recently, there is a lot of class (about 70 class, 30 student/class) attempt quiz at the same time, LMS is very slow at this time. the quiz has period is about 20 minutes.
The model server LMS have two servers (1 webserver( 10CPU, 20GB RAM), 1 database server(22 CPU, 30GB RAM)
I would like to build a new LMS but also using moodle open-source. However, I haven't an optimal model for moodle yet. Additional, I would like to use the moodle app on mobile, how can I build it.
I hope the experts help me make recommendations on the optimal model for the system running moodle.
thank you so much
