Reponse time diiference between local host and stormrunner

Hi Everyone,

I want to know what is happening when we are running the test from local machine and when we are running it from stormrunner and how it is creating difference in response timings.

I have a Web application whose response time for a particular page is 12 secs in firebug but when i am running the same script in stormrunner i m getting around 5 secs. Or can anyone suggest some link from where i can get this basic information.

Thanks in advance.
