Why does TomCat have a slow response time?

How often do I get slowdowns on Tomcat?
We get the slowdowns several times a week, where Tomcat will stop responding or take several minutes to process requests, and the cpu loads on the (Linux) box, as shown by uptime, spike from typically around 1-2 to over 30. Then things gradually work themselves out and everything goes back to normal after maybe 10 minutes or so.

How big of a heap do I need for Tomcat?
I’d note, if you haven’t already done so, bump up the tomcat heap size to somewhere around 1/2 to 3/4 available memory assuming this box JUST runs tomcat.
