  • 64bit SUN JDK 1.7 and above – we recommend using SUN JDK. We have not tested with other JDKs

  • We recommend a heap size of 6GB.

  • We have seen best performance with these JVM GC options for our apps

    "-server -Xms6g -Xmx6g -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+UseCompressedOops -X:MaxTenuringThreshold=8 -XX:CMSInitiatingOccupancyFraction=75 -XX:MaxNewSize=3g -XX:NewSize=3g -XX:+CMSConcurrentMTEnabled -XX:+CMSScavengeBeforeRemark"

  • For applications requiring processing rates of 10000 events per sec we recommend using 4 cores with hyper threading with minimum 12 MB Cache for good performance

  • Do not use IPV6 interfaces or IPV6 stack - Jetstream does not support IPV6 at this point.

  • You must use maven 3.0.5 and higher for building your application with jetstream libraries.
