Have you configured JVM parameters when launching applications?

Yes, JVM parameters are often tuned to optimize application performance. For example:

• -Xmx and -Xms set the maximum and initial heap size to control memory usage.
• -XX:+UseG1GC enables the G1 garbage collector for improved performance and reduced pauses.
• -XX:MaxMetaspaceSize limits the size of the metaspace.
• -XX:+HeapDumpOnOutOfMemoryError creates a heap dump when an OutOfMemoryError occurs.

An example of running an application with parameters:

java -Xms512m -Xmx2g -XX:+UseG1GC -jar app.jar

Configuration depends on the application's requirements and environment, so profiling and testing different parameters is important.
