Управление использованием памяти
| If you are certain your webapps need a lot less than half a gig memory,
you can start Tomcat with a smaller maximum heap by setting the
environment variable CATALINA_OPTS to "-Xmx256m" in catalina.sh to give
it a maximum heap of 256MB. If your app sometimes needs more memory but
you want it to shrink down its heap more quickly, set it to
"-XX:MaxHeapFreeRatio=20 -XX:MinHeapFreeRatio=10" - this will give back
memory to the OS if more than 20% of the heap is free after garbage
collection, and expand the heap if less than 10% is free. But this may
reduce performance by making Java spend a lot of time allocating memory
from the OS and freeing it again soon after.
