How to test load (performance) when web application is running on sever?

Madhu Sudhana Reddy said...

Every server has unique IP address or Domain name, and every application or service is run on unique PORT. So take the IP address and Port number then you can test the application.

Ex:
My server IP/Domain name is google.com and My Application is running on 80 port . So you can access the application using http protocal , see below

http://IP address/Domain:80
so i can access google.com like this
http://google.com:80/.
