ASP.Net Website slows down when hosted on server

Hi,

My asp.net site has very good performance on local ips on all the systems. But it 5 time slow down on live ip.

1. What could be the issue:

Server is not capable? I have checked the ping and it response time is 153 ms for each require on live ip but on local ip it gives < 1 ms response time.

2. I have not compile the solution just copy and paste on the iis and create virtual directory? is this a problem

3. or any other thing? please guide.
