When a file is commonly used, web-servers are performing various
optimizations, like
putting them to memory, caching, etc

The application response delay is a complex function of both your
application and your server,
where each may be doing optimizations for commonly used data and files.

When your server will be have e.g. half used CPU, memory mostly used, etc
you will start to see
see, that the application response time starts being longer.
Take care about the potential network bottleneck, so that you'll have always
enough
bandwidth in order to measure exactly what you want: the server application
delay and not
any network effects.
