The > question is really how much hardware is "appropriate"? It'll all depend Let's be more specific. We expect something like 50 users making 5000-row queries (Oracle database) on a _huge_ table simultaneously ( plus more that 200 of them doing smaller ones). There are currently 200-300 new user connections per minute and it's growing. Hardware is not a problem, but I'm concerned about what happens to a Apache/PHP3(4) server handling that load (stability problems, certain bugs showing, etc?).

What's that?

OK, but I need CORBA just for limiting the count of concurrent database connections and for intelligent request queuing. Are there any other (already implemented) solutions for that?
