Howdy,
You can run tomcat 4.x and 5.x with less than 8MB of RAM. It all
depends on what webapps you have configured, connectors,
min/maxProcessors, etc.
The more general question of heap size vs. overall OS process size is
far more difficult to answer. The answer is highly variable from one OS
to another and from one OS version to another. Generally speaking, as
the size of the heap is larger the ratio of the heap to the process size
nears 1. In theory it can never reach 1, it's at best slightly less.

A basic out of the box Tomcat 5.0.12 is pretty happy with around 30MB
on a
windows machine, but it's always tricky to say how much memory it will
use
as it depends on lots of other things, how you configure it and the
kind of
applications you run on it, but 40-50MB could be an ok guess on
Windows.

Subject: How much memory does Tomcat really use?
Does anyone have a handle on how much memory is used by java in
running
tomcat? I set the ms and mx values but it always seems that the
process
overall takes up much more memory.
I asume it's overhead with the JVM talking to the operating system.
I'm trying to get a handle on how to size various servers.
I went through Sun's developer forums and I've seen this question
asked
several times with no response.
I work in bothe the Solaris and windows environment.
Thanks
