In the jvm.xml file there are already some settings given as an example.
<Option Name="-Xmx" Value="50m"/>
<Option Name="-Xms" Value="20m"/>
<Option Name="-Dfile.encoding" Value="UTF-8"/>
It is possible to add other JVM options to Tridion jvm.xml file, like -XX:MaxHeapFreeRatio, and how, i.e. will the JVM initialization methods actually take them into account?
If the answer is yes, does it actually help decreasing the size of the spawned JVM?
<Option Name="-XX:MaxHeapFreeRatio" Value="60"/>
?
