The best thing to do with this problems is to plan it throughly. Having a lot of computers certainly slows down the internet connection thats why proper maintenance of the facilities is required. Regular check-up of the devices is a must, although this does not directly affect the connection, but having a slow pc unit plus slow internet would mean that your not getting the services you paid for. Maintenance would include fixing pc hardwares and peripherals, removing existing viruses and updating the anti-virus databases.

Now for the connection itself, decide on what network topology best fit for campus use. Check the connecting wires and ensure that it is working properly (check either may gasgas yung wire o may sira sa mga rj-45). I don't know how many ISP the school is subsribed to, but if there are more than one, it would be best to divide it per building/s.I think its better to have two regular-speed connection providing each a half of the units in the campus, rather than having one upgraded connection used throughout the university.

Also, since the E-Library is made for educational purpose of the school, streaming through unnessesary sites should be restricted.
