Re: PHP Performance/Scalability

Hello Deepak, 

1500 as concurrency is very very high. It means there are 1500 ongoing HTTP requests. They started and didn't finish yet at the same time. This can only happen when your average response time is high. What is your average response time?

Hello

I have a very simple PHP application which I develop on Apache-Web-Server. However the application does not scale beyond 1500 concurrent users (150 requests/sec), even though there is plenty of hardware available (CPU is getting utilized 15%, Memory is getting utilized 15%).

On a similar note, when I develop the same application in Java, it scales to more than 6000 concurrent users (600 requests/sec) on the same hardware.

Any pointers on how to address this scalability issue?

Thanks!

Deepak
