MinHeapFreeRatio and MaxHeapFreeRatio (divided by 100). This is used, in 
case you configure your maximum heap size different from the minimum 
heap size. If after GC less than the min percentage of heap is free, 
heap will grow, if more than max percentage is free, heap will shrink.

In your case 10% resp. 30%.

BTW: that's a general Java question, not Tomcat specific.
