Peter is correct - I was just being a bit lazy in my answer...
The ssl connection is setup BEFORE any 'hostname' information is
passed over the link, and therefore the server would not know 'which'
virtual hostname's ssl certificate to use.
Therefore - 1 certificate per IP Address/ Port

What is this supposed to become?
Do you want 10,000 domains on the tomcat? or do you want 10,000 webapps?
The JVM will die if you do this with 10,000 webapps

Ok - Theoretically it may work...
Who do you know that has a machine with Terabytes of memory? And is
using it for web hosting?!
The JVM will spend all its time doing context switching and garbage
collection...

If you are only delivering static content, then use Apache or Lighttpd
http://www.lighttpd.net/
This is NOT what tomcat is designed for
As for how much memory, no idea - but it cant be good

Dear Mladen,
Are we referring to 10,000 Virtual servers or 10,000 Connections?
And the answer is yes to 1 connections.
Yes I would use worker-mpm or better still an epoll based httpd
daemon, like lighttpd or zeus.

Stupid question,
Why don't you implement the 'virtual' hosts inside the one 'webapp'?
And not create 10,000 web apps?
That the App itself deals with the virtual hosts (by reading the host
header), and not tomcat?

Why do you need c?
Works with perl and shell scripts...
You could even use java if you wanted

Which kernel are you using? 2.6 or 2.4?

I discovered no difference in performance between running 1 tomcat, or 4
tomcats on the one machine - same performance.
The machine was a 4x Opteron 870 with 8GB RAM, running Java 1.5.6 32bit.

Hi Rodrigo,
How long is a piece of string?
The 'Brand' of linux only really makes a difference for
administration purposes. Performance will be about the same on all,
depending mainly on which version of the kernel you are running.
Should you decide to go Linux, I would look at something
Hi Nicolas,
Tomcat works best with large hardware. I have found that using a Sun
Enterprise 15K with 1 processor per online user gives me the best
performance.

You may want to try turning off keepalives in your tomcat. (I assume
you are only using tomcat, and not proxying through mod_jk and
apache/ IIS).
In your connector settings have a look at 'maxKeepAliveRequests=1'
If you really have that many threads, you will probably be best of
using
