Do you have any actual problem that you are observing? Frequent young-generation GC:s (ParNew) are expected. If you want to cut down on the length of them you may want to change the JVM settings in cassandra-env.sh to use a smaller young-gen, but that will probably cause overall GC cost to go up as more data is promoted into old gen. -- / Peter Schuller (@scode on twitter)
