Subject Re: -Xmx/-Xms Parameters, Where do they go???
Date Mon, 24 Jun 2002 21:18:23 GMT
I've added a line in my tomcat.sh that sets the TOMCAT_OPTS variable. 
You should really set "-server" since I've seen noticeable improvements 
over the "-client" option (which is the default). "-server" must be the 
first option. Then, use -Xms and -Xmx to increase your memory 
allocation. If you are using 1.3.x, you should look at -XX:NewSize and 
-XX:MaxNewSize for much larger mx/ms values. You can find more 
information about these at http://java.sun.com/docs/hotspot/index.html
