+1. Heck, just upgrading to a 1.6 JDK should give a noticeable improvement.

Definitely 6.0.24 (or whatever's current when you do move up).  Also use JDK 6, 
which is measurably faster than 1.5 in most circumstances.

There's not much point in trying to optimize an unsupported, six-year-old 
version of Tomcat.  Your time would be better spent upgrading to a current 
level, which includes significant performance improvements.

Tomcat is pure Java, so it's independent of architecture.  If you're running 
Tomcat as a service on Windows, you will need to get the 64-bit version of the 
service wrapper (tomcat5.exe).  Get it from here:
http://svn.apache.org/repos/asf/tomcat/tc5.5.x/tags/TOMCAT_5_5_28/connectors/procrun/bin/amd64/

(The 5.5 tomcat5.exe will work on 5.0.)

Don't wait too long - the version you're on is almost six years old and hasn't 
been supported for quite some time.

Tomcat is pure Java, and is therefore not compiled for any particular
word size.  You may be using native libraries which are compiled for
particular architectures, but Tomcat itself will run quite happily on
a 64-bit JDK.
