10,000 connections and 10,000 virtual hosts have NOTHING to do with
one another.
As to 10,000 virtual hosts in Tomcat, vs 10,000 virtual hosts in
Apache....
No idea - I don't think 10,000 virtual hosts on either is a good idea.
But with Tomcat, you have 10,000 'WebApps' ie: at least 10,000
objects, ignoring what ever else the webapp initialises, vs a look up
table (probably a hash) in Apache.
I don't think it is a very scalable solution.
According to the original poster, all 10,000 webapps, are the same,
so I would look at only having 1 web app, and dealing with the
'virtual hosting' inside my webapp.
That could be a good move. A JSP like the index.jsp which is in Tomcat
could do that, and is at least as fast as a static page.
Note: If APR is installed, Tomcat uses epoll if available too, so it
can support 1000s of connections easily (on Linux).

I think the OP said that their current solution *does* use a single
webapp & a filter to select the correct part of the filing system.
Without wanting to get into an ideological httpd vs tomcat, I'd suggest
that the if the OP wishes to conduct tests, that he familiarises himself
with the sendfile & mmap directives, and mod_vhost_alias module of
Apache HTTP.
The combination is likely to provide the best solution that HTTPD alone
can offer.
With regard to Tomcat, as a standalone, it will not compete with HTTPD
unless APR is correctly installed.
Overall, if the OP is serving static pages, then the likely best fit is
to use a Tomcat webapp (available in all vhosts) to manage the sites,
write them out as static files and then serve them using a nicely tuned
Apache.
