Profiling Your Java 8 Game Application CPU Usage
Chapter 2 ■ Setting Up Your Java 8 IDE: An Introduction to NetBeans 8.0
Using the Profile Project menu item or shortcut icon will open the Profile InvinciBagel (your game project’s name)
dialog, as shown in Figure 2-14. Let’s click the center CPU button at the left of the dialog, which will put the dialog in
Analyze Performance (selection characteristics) mode. You will look at profiling memory use a bit later on (see the
section “Profiling Your Java 8 Game Application Memory Usage”). The Monitor (button) option enables real-time
thread monitoring, which can be used while you write your Java code.
Figure 2-14. Set the filter, using the drop-down menu in the Profile Project dialog, and select the Advanced
(instrumented) output setting
In this dialog, you can select a Quick profile or an Advanced profile, which has graphical instruments that show
the performance visually. As you can see, this is the option selected as well as the Profile only project classes option
from the Instrumentation Filter drop-down menu. Leave Use defined Profiling Points selected to get NetBeans 8.0
to do the maximum amount of profiling work possible. Note as well the Overhead gauge (indicator) at the bottom of
the dialog, indicating a 50 percent value.
The first time that you run the NetBeans profiling tool, it needs to calibrate your workstation, as every
workstation will have different characteristics, such as the amount of memory and number of CPU cores, or
processors.
