Performance Issues

Question

Dear All,

 

Recently we have deployed “Web Application” in client environment .

 

Client is saying there is performance issue.

 

Following are some input.

 

1. Client is connected to server using remote admin (the server where application is deployed), An access application using http://localhost/ on remote server itself/ (Why don’t know)

 

2. Web server and Database servers are different.

 

Ps – its working in our environment very fast.

 

What all the various things I can try here to diagnostic the root cause.

 

What all various things I can ask from client to do further analysis.
