Suppose you were using statistical software to evaluate the performance of various HTTP server packages. What would be the most efficient way to compare performance data accurately?

A.
Gather real-time performance data on each server by running several system-monitoring applications on the server at one time.

B.
Request that vendors provide their benchmark results of running a standard monitoring application.

C.
Install resource-monitoring software on each server independently and vary the actual load conditions on each server.

D.
Use a remote computer to capture statistical information on each server operating under a simulated load.
