GC Tuning

Java GC tuning options that work for me with Solr on 64-bit CentOS 6 with Oracle Java 7:

-XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=75
-XX:NewRatio=3
-XX:MaxTenuringThreshold=8
-XX:+CMSParallelRemarkEnabled
-XX:+ParallelRefProcEnabled
-XX:+UseLargePages
-XX:+AggressiveOpts

I got a recommendation on IRC for a simpler alternative. One day when I find the time, I will do some more extensive testing.
