I am marking a online examination web portal for my college. I am using code Igniter for it. Recently one staff member told me that you need to optimized your code as I would fail if 100 student will give test concurrently.
I tested it with 2 user and I am having only 2 devices. Its working fine.
My question is, Can I automate the process for test purpose? Like wise 100 user get created by the testing tool and 100 concurrent process starts. What I do with a single user, same tool must do with 100 user.
Any suggestion how I can optimized my portal for concurrent sessions.
