Marius van Voorden created OPENMEETINGS-569:
-----------------------------------------------

             Summary: Faulty highperf settings in bat script
                 Key: OPENMEETINGS-569
                 URL: https://issues.apache.org/jira/browse/OPENMEETINGS-569
             Project: Openmeetings
          Issue Type: Bug
    Affects Versions: 2.0 Apache Incubator Release, 2.1 Apache Release
         Environment: Windows
            Reporter: Marius van Voorden
            Priority: Minor
             Fix For: 2.0 Apache Incubator Release, 2.1 Apache Release


The current red5-highperf.bat has the following java options:
set JAVA_OPTS= -Xmx768m -Xms256 -Xmn512m -Xss256k -XX:+AggressiveOpts -XX:+DisableExplicitGC
-XX:ParallelGCThreads=4 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:SurvivorRatio=16 -XX:TargetSurvivorRatio=90
-XX:MaxTenuringThreshold=31 -Djava.net.preferIPv4Stack=true

There are two issues:
Xms256 is missing an "m"
Xms needs to be larger than or equal to Xmn

Suggested fix:

set JAVA_OPTS= -Xmx768m -Xms512m -Xmn512m -Xss256k -XX:+AggressiveOpts -XX:+DisableExplicitGC
-XX:ParallelGCThreads=4 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:SurvivorRatio=16 -XX:TargetSurvivorRatio=90
-XX:MaxTenuringThreshold=31 -Djava.net.preferIPv4Stack=true
