I am building a PHP-MySQL website featuring an online contest and my client needs an estimate on the maximum possible number of users logged in at the same time that the website can withstand without slowing down. I have tried to minimize the number of HTTP request and even optimized it very much but I can not give a number of maximum users.
I have set the MaxKeepAliveRequests to 0 to disable the maximum cap.
The site is on a shared hosting server. Is there any method to estimate the maximum safe limit of number of users.
The site is built on Yii framework.

Performance estimations are pretty much useless.
So don’t estimate – measure. Use a load testing tool like Apache JMeter or a service like Blitz to actually simulate lots of users and see what happens.
