As soon as you start swapping the performance will become abysmal ... 
so, you need to pick a size that still can hold your index but doesn't 
cause swapping. 512M? 768M? who knows ... Please check Tomcat 
documentation on how to set it properly - I usually don't bother with 
the "proper" way and hardcode this value in catalina.sh script ... ;)
