<br>
I think this is a question better suited to be ask of the Tomcat
folks.<br>
<br>
You are holding the Java version the same and changing Tomcat.
That implies the increase in memory consumption is a from a change
in Tomcat, not a change in your Java version.<br>

<p>Hi OpenJDK support team,<o:p></o:p></p>
<p>While upgrading Tomcat from tomcat 6(6.0.28) to tomcat 7
(7.0.54). the following problem happens. TOMCAT 7 (7.0.54)
memory consumption increased about approx. 3 times compare to
the existing tomcat 6 (6.0.28) memory consumption.<o:p></o:p></p>

<p>The underline JVM is <o:p></o:p></p>

<p>Underline java platform is same(OpenJDK7) in both tomcat 6

increased about 3 times in Tomcat 7.<o:p></o:p></p>
