We're currently using JDK 8 update 5 with the following settings: -server -Xms4g -Xmx4g -XX:PermSize=96m -XX:MaxPermSize=96m -XX:+UseG1GC -XX:MaxGCPauseMillis=20 -XX:InitiatingHeapOccupancyPercent=35 -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps -XX:+PrintTenuringDistribution -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintTenuringDistribution -Xloggc:logs/gc.log -XX:ErrorFile=logs/err.log
This works well for us, but you should customize it to your workload. :) -Jon On Jan 14, 2015, at 5:51 PM, Albert Strasheim <full...@gmail.com> wrote: > Greetings all > > We're expanding our Kafka cluster, and I thought this would be a good > time to try the suggestions in > > http://www.slideshare.net/ToddPalino/enterprise-kafka-kafka-as-a-service > > slide #37 about running on JDK 7 with G1 GC. > > Anybody (Todd?) that could shed some light on a complete set of good > GC flags to start with and what the best JDK version is to run with > these days? > > Thanks! > > Regards > > Albert
