how much does this script handles ??!! hmm
well gotta say that this is an important question but it's not about the script it's about the server
the server handles the users and not the script so when you have , lets say , a cluster then you will be able to handel the unlimited users (with 200 000 online at the moment )..
a top server will be able to handle as much users as you want but no more than 10000 users online
cuz when a user register he only takes a place in the hdd but the performance is measured y active users cuz those how do stress the server
i.e. :- the script is just a form so lets say you have a join script with a data base this script is really simple but if you have many users using it then you should get a really nice server .. cu the only thing this script do is to order the server.. so the script it self has nothing to do with the users ..
also you can use a Benchmark Performance Script to test dolphin
