Figure 2-15 displays the Calibration Information dialog, which suggests that only NetBeans run on your
workstation during the calibration process and tells you how to calibrate again in the future (if you change the
system hardware configuration), using the Profile ➤ Advanced Commands ➤ Manage Calibration Data menu
sequence.

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 involves 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 relative 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 version), you will probably get a
Windows Firewall has blocked some features of this program Windows Security Alert dialog. You want to have
all the features of NetBeans 8.0 at your disposal, so let’s look at how to allow access to the Java SE 8 platform in
Windows next.
