Optimizing Java Runtime Memory usage is a bit of a black box art. The two most important options are-XMX and-XMS. There are other parameters, depending on the Java runtime version and the operating system. -XMX sets the maximum heap size that can be used by the Java runtime. -XMS just set the initial heap size. The default value depends on the operating system and the Java Runtime version, but the default value for general-xmx is 1MB.

Brain storage Conversion is 1024 to 1 units, that is to say 1m=1024k, 1024m=1g,1024g=1kg, but computer hardware is calculated in 1000 units, that is, the capacity of storage devices such as hard disk (such as 80G hard disk) =8000m, There is a storage error between the hardware and the software.
Normally, the M unit reads "Mega" sign bit MB abbreviation m, and its conversion units are:
