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?). Anyone wanna share experiences?

ZendPersistentRegistry? What's that? Does it allow to to have persistent variables that preserve their values while PHP parses several documents?

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?
