Moodle is one of the most popular Learning Management System (LMS) in the world. However, this kind of system always suffer the burden of large amount of user connections in a short period of time, such that the front end web servers and the rear end database servers became the bottleneck of the whole system. In the LMS system, the most challenges are to provide the rapid response, the system stability, the system flexibility, the system scalability, and the fault tolerance. Currently, the problems of system overloading are solved by the load balancing scheme, which still have a lot of limitations. In this paper, the proposed scheme, based on the load balancing scheme, combines the mercy of Moodle network scheme and the separate of database in order to improve the performance both on the level of systems and applications for the situation of large amount users. From the performance evaluation, the proposed scheme is superior to the existing system model.
