| <section name="Performance Tuning"> | |
| <p>To use the optimum of performance from your server there is a | |
| start-script for red5 available that does some basic settings in the | |
| JVM. It is called red5-highperf.sh. It is recommended to use that | |
| script for production and high-load scenarios. | |
| </p> | |
| <div class="xmlcode"> | |
| #!/bin/bash | |
| <br /> | |
| <br /> | |
| if [ -z "$RED5_HOME" ]; then export RED5_HOME=.; fi | |
| <br /> | |
| <br /> | |
| # Previous option set | |
| <br /> | |
| export JAVA_OPTS="-Xrs -Xms512M -Xmx1024M -Xss128K -XX:NewSize=256m | |
| -XX:SurvivorRatio=16 -XX:MinHeapFreeRatio=20 | |
| -XX:+ExplicitGCInvokesConcurrent -Djava.net.preferIPv4Stack=true | |
| -Xverify:none" | |
| <br /> | |
| <br /> | |
| # start Red5 | |
| <br /> | |
| echo "Setting Hi Performance Options" | |
| <br /> | |
| exec $RED5_HOME/red5.sh >> $RED5_HOME/log/jvm.stdout 2>&1 & | |
| <br /> | |
| </div> | |
| <p>You have to exclude the "-XX:+UseConcMarkSweepGC" param from the | |
| default red5-highperf.sh to make it functional! However if you are a | |
| performance expert you might also play with the values to find | |
| perfect matches for your use-case. | |
