rem   =====================================================
rem   Environment variables that can be defined externally:
rem
rem   Do not set the variables in this script. Instead put them into a script
rem   setenv.bat in JMETER_HOME/bin to keep your customizations separate.
rem
rem   DDRAW       - (Optional) JVM options to influence usage of direct draw,
rem                 e.g. '-Dsun.java2d.ddscale=true'
rem
rem   JMETER_BIN  - JMeter bin directory (must end in \)
rem
rem   JMETER_COMPLETE_ARGS - if set indicates that JVM_ARGS is to be used exclusively instead
rem                 of adding other options like HEAP or GC_ALGO
rem
rem   JMETER_HOME - installation directory. Will be guessed from location of jmeter.bat
rem
rem   JM_LAUNCH   - java.exe (default) or javaw.exe
rem
rem   JM_START    - set this to 'start ""' to launch JMeter in a separate window
rem                 this is used by the jmeterw.cmd script.
rem
rem   JVM_ARGS    - (Optional) Java options used when starting JMeter, e.g. -Dprop=val
rem                 Defaults to '-Duser.language="en" -Duser.region="EN"'
rem
rem   GC_ALGO     - (Optional) JVM garbage collector options
rem                 Defaults to '-XX:+UseG1GC -XX:MaxGCPauseMillis=100 -XX:G1ReservePercent=20'
rem
rem   HEAP        - (Optional) JVM memory settings used when starting JMeter
rem                 Defaults to '-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m'
