<h3>Optimization (OPTIMIZE)</h3>
|
||
|
|
<p>Specifies how to treat class files if no Java program is associated with the file.
|
||
|
|
</p>
|
||
|
|
<p>For 10,20,30,40 this specifies the optimization level of the Java program which will be created if no Java program is associated with the Java class file. The Java program will contain machine instruction sequences that are run when the Java program is invoked and will remain associated with the class file after the Java program has been run.
|
||
|
|
</p>
|
||
|
|
<p>If the Java class file is determined to be downlevel or out of date, a new Java program will be created using the optimization level that was used when the previous Java program was created, instead of the value specified for this parameter.
|
||
|
|
</p>
|
||
|
|
<p>For OPTIMIZE(*INTERPRET), the resulting Java program interprets the class byte codes when invoked.
|
||
|
|
</p>
|
||
|
|
<p>OPTIMIZE(*INTERPRET) Java programs will be smaller but will run slower than Java programs created with higher optimization levels. As you increase the optimization level beyond 10, the Java program performance will generally improve, but the time required to create the Java program will increase and you will have less ability to debug the Java program.
|
||
|
|
</p>
|
||
|
|
<p>For OPTIMIZE(*JIT), no Java program containing machine instruction sequences is created if no program is associated with the class file. Rather, the class is run using the Just In Time compiler (JIT).

|

|

<p>Specifies the maximum size, in kilobytes, that the garbage collection heap can grow to. This is used to prevent runaway programs that consume all of the available storage. Normally, garbage collection runs as an asynchronous thread in parallel with other threads. If the maximum size is reached, all other threads are stopped while garbage collection takes place. This may adversely affect performance.
