How do I set a memory limit for my JVM application?

Setting Maximum Memory Usage for JVM

Optimizing memory usage is crucial for minimizing latency and improving performance in Java Virtual Machine (JVM)-based applications. When running a JVM-hosted application, it is necessary to define the maximum memory it can utilize to prevent excessive memory consumption and system instability.

To establish a memory limit for the JVM, employ the following arguments:

-Xms and -Xmx

• -Xms: This argument specifies the initial or minimum memory allocated to the JVM at startup. As the application runs, the JVM may dynamically adjust the memory up to the maximum limit specified by -Xmx.
• -Xmx: This argument defines the maximum memory the JVM can use. It represents the hard limit beyond which the JVM cannot allocate any additional memory.

To indicate the memory size, use suffixes M or G after the numerical value to represent megabytes and gigabytes, respectively. For example, to set the minimum memory to 256 megabytes and the maximum memory to 1 gigabyte, use the following arguments:

-Xms256M -Xmx1G

The -Xms and -Xmx arguments provide granular control over the JVM's memory usage, allowing you to optimize performance and prevent resource exhaustion by limiting the total memory consumption of your application.
