Tony,
The performance numbers you are talking about are going to be
irrelevant over any but the fastest local links, particularly using
TCP. RTT below 30ms are going to be rare within the US and even on a
very good tier 1 provider (Verizon/Qwest) directly you're not going
to get much better.
I think you've got yourself locked in to an idea of how to solve a
problem without either a measurable problem or the right idea of a
solution.
In your situation your solution might be to setup a caching proxy
server on port 80 with apache and tomcat on different ports and use
the proxy server to handle the requests. It should be able to handle
static content with much less resources than Apache can. At this
point you can tune apache down to the bare minimum. As latency is
very low it shouldn't need many processes to serve all requests.
Further if Apache isn't necessary for anything you could serve the
static content from Tomcat and cache it in memory on the proxy.

Hi Jeff,
I would agree except the current audience using my
portal is from all over the world so performance &
size of data is critical. Also with an upcoming GA
release the inital audience may be higher than a
million or so and grow hopefully quickly from there.
The system is using an RIA client to reduce the stress
on the servers but the goal is to have the worlds
fastest least expensive portal.
I have already gotten comments from clients thousands
of miles away from the server of how the performance
is such that the clients think the data from my server
is faster than off a local hard drive.
That only happened because of the performance was
considered as important as the functionality and still
is as you can tell.
Good point for most systems.

Tony,
I agree with Joshua: quite complicating things for
yourself.
It sounds like you are trying to solve a performance
problem of some sort
but speaking from experience those are highly
dubious pursuits unless you
have a very, very well qualified issue. Otherwise,
it's purely academic
IMHO. I don't remember where I read this but the
rules for performance
tuning are something along the lines of:
1. Don't
2. Don't yet (for experts only)
My advice, don't worry about performance until there
is a qualified
performance issue (i.e. one identified by a
customer/end user) and stick
with the Apache/mod_jk/Tomcat reverse proxy
configuration since it's an
industrial strength solution.
Cheers,
Jeff

Quit complicating your life. There are at least
three easy solutions
to your problem:
1. Tomcat CAN serve static content. So just use
tomact and forget
about apache httpd.
2. Use a standard apache httpd+tomcat install.
Lots of people do this
and it is plenty performant and not that
complicated.
3. Put the two on different ports (assuming your
ISP doesn't block
non-80 ports).
