wrapper.java.initmemory Property
wrapper.java.initmemory Property
Configuration Property Overview
wrapper.java.initmemory

The initial amount of memory in megabytes that the JVM should allocate at startup. Defaults to 0, which will cause the JVM's default value to be used.

If a non-zero value is specified for this property then an appropriate -Xms parameter will be added to the Java command generated by the Wrapper. If specified, the initial memory must be less than or equal to the value set for the wrapper.java.maxmemory property.

If this property is set to 0 then it is also possible to specify the -Xms parameter manually using the wrapper.java.additional.<n> property.

This value can affect the startup time of the application. Startup time is optimized when this value is fairly close to the actual amount of memory required by the application once it has been started. The default value for Windows and Linux JVMs is usally 2Mb, but Solaris JVMs require a minimum of 3Mb. Valid values are in the range 1 to 4096Mb.

Example:
wrapper.java.initmemory=3

NOTE

Unless you really do know everything there is to know about memory and Garbage Collection in Java, I would recommend reading through the following document. It describes in detail how the initial and maximum memory values affect Java performance and also goes into detail about what can be done to improve that performance for a given application.
