Command-line options and environment variables that can affect the performance characteristics of the Java Virtual Machine

There are several categories of JVM arguments:

  1. Standard options recognized by the Java application launcher (e.g. -client, -classpath, ...)
  2. Options that begin with -X which are non-standard (not guaranteed to be supported on all VM implementations) and are subject to change without notice in subsequent releases of the JDK (e.g. -Xbootclasspath, -Xms, -Xloggc, ...)
  3. Options that are specified with -XX are not stable and are subject to change without notice (e.g. -XX:+PrintGCDetails, -XX:-UseParallelGC, ...)
