Hi guys. Is there a way to reduce the number of processes that ES spawns?  
With an index that's less than 20MB, htop shows 43 of these processes:

/usr/lib/jvm/java-6-openjdk/bin/java -Xms16m -Xmx64m -Xss128k  
-XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled  
-XX:SurvivorRatio=8 -XX:MaxTenuringThreshold=1  
-XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiati

Thanks,  
Nick

Nick,

I think you are seeing threads, not really processes.

You're right, Otis! Thanks for that. I completely forgot about hiding  
threads.

Cheers,  
Nick
