Hello all,
We run tomcat inside an embedded system and we are planning to upgrade the
tomcat version from 3.3.1 to 5.5.16. We noticed that the memory footprint of
a barebones tomcat 5.5 installation is 44 MB. Plain and simple Tomcat 3.3
used to run with 25 MB. We have limited memory on our

2) Remove unwanted jars from WEB-INF/lib and also from
tomcat-home/common/lib
3) Also remove wherever the jars seem to be unnecessary.

Hey thanks for your comments -
1. Our applications are fixed. We have removed all unnecessary apps.
2. Unwanted jars/classes are not loaded into physical memory by IBM JVM on
Linux. So, it will not add to RSS. We have done some experiments and are
sure of this claim.

Hi,
This question was asked (yesterday) by myself. Firstly, stop using JK2.
Secondly, go read
http://www.adcworks.com/blog/index.php/2005/08/03/load-balancing-with-tomcat-55-and-jk-12/
Which explains how I have 2 Tomcats up on 1 server.
Cheers, Allistair.

thanks for your very quick response.
The link you mailed does not work, please resend the correct link.
Also: I do not use TC load balancing, but completley separate TC,
which must run independant of eacch other on the same Linux server.

Yes. Clone the entire installation several times. This has the

you can configure the tomcat classloaders via catalina.properties. Look

why the common loader finds code in CATALINA_HOME/common/lib/*.jar, but
not in the analogous CATALINA_BASE

Is there some documentation on how much memory a typical Tomcat 5.5

It takes about 45 MB (resident set size, ps -eux) on my linux system with

most of that is the IBM VM, plug in a profiler and you'll see that
tomcat should be around 10MB or less

Hi Filip,
I am not convinced with your argument. When I start Tomcat 3.3 with the same
JVM, same OS and same heap -X settings, the RSS barely crosses 25 MB. Tomcat
5.5 takes 45 MB. In both cases, there are no webapps...and all
conceivable settings, threads, listeners are same.
