Usage:


 This flag disables the JVM to monitor and performance testing.

 

Since:

 

Starting from JDK 6.

 

Examples:

 

To disable performance data:

 

java -XX:-UsePerfData MainClass

 

Description:

 

By default, the jvmstat tool in the HotSpot JVM is turned on. JVM option -XX:-UsePerfData turn off the monitoring and performance data. So the downside of turning it off is that you lose performance monitoring information and you won’t have the creation of the directory “hsperfdata_userid”.

 

Default Value:

 

By default, this flag is enabled.
