It's not AR System 5.1.2 and it's not Tomcat 5.0.30 - but there is a
white paper on Tomcat performance as a plug-in vs. standalone in terms
of AR System 7.0.01 and Tomcat 5.5 available on the BMC support site:

Subject: Mid-tier performance

Hi Folks,

I have a question about Mid-tier performance between the following two
configurations:

1. Running Tomcat server (version 5.0.30) as both the JSP server and
    the web server.

2. Running Tomcat server (version 5.0.30) as the JSP server and Apache
    as the web server, using the Tomcat-connector.

I have asked my local support folks and thay said "it depends on the
type of content that you are serving".

I presume that the Apache server is a better http server, but is that
outweighed by the overhead of having to ship everything through the
connector to get it to the JSP engine?

I am currently running it in the first configuration and it seems Ok
except that it is pretty sluggish. The mid-tier machine is not doing
anything else... completely unloaded. It is a development box that
someone has loaned me for testing.

Here are the specifics of the configuration:

ARS server 5.01.02 Patch 1313 on Sun Solaris 8 DB is Sybase 12.5.2, also
on Solaris 8.
Mid-tier 6.3 on a dual processor (each 2.8 Ghz.) Sun V65X 2 Gig of
    RAM running Red Hat Enterprise Linux AS release 4 (Nahant Update 4)

Thanks for any insights you might have on this.
