Hi,

I have used Xampp for developing a PHP applications.

That application must run in a DMC machine with a lot of proxies and firewall

This application will be having 1500+ hits in the same time, it can have 1500 concurrent users.Does Xampp id that much stable to handlle this much of users?.Also application will run successfully for this much of users???

Also how can I improve performance of Xampp???.Let me know

Xampp is just an easy-to-install packaged version of Apache, MySQL and PHP. Both Apache and MySQL are very scalable and robust.

You can install e-accelerator to speed up PHP performance. The speed boost is just amazing.

Any more hints to speed up the performance?.Does it can handle 2000+ concurrent visitors???

When we tried load testing using OpenSta, it is failing for 19th concurrent visitor.It is tested using virtual user option.So we are worried about 2000+ concurrent users.

Any tips??, how we can make it stable???? plzzz

What you should really looking for is to tune apache for high traffic. Just Google for "configure apache high traffic" and you will get a lot of articles on this.
