There is also a warning, saying that you should
disable dynamic CPU frequency
switching
(this is typically referred to as overclocking), which is a common feature
these days.
Because I want to test for slower CPU speeds, I did not bother to do this, as it in-
volves going into the system BIOS (Basic Input/Output System) on the workstation
motherboard and is not something for beginners to be playing around with.
Ultimately, the most thorough way to test a game application is across a wide range
of different OSs and hardware configurations, but I wanted to show you this profiling
feature, as it is a great way to get a good baseline on your application performance,
which you can then improve on as you refine your code (and then run the profiler again
and again, comparing the results with the original baseline measurements).
Once you click the OK button, NetBeans IDE 8.0 will calibrate its profiling tool re-
lative to your system hardware characteristics, which should not take long at all on a
fast, modern-day, multicore workstation.
If you are running the Windows OS (as seen here, in the 64-bit Windows 7 ver-
sion), you will probably get a
