My experience is of dealing with servers where each machine typically has= a small number of important applications -- frequently only /one/ applica= tion -- which it has to run as efficiently as possible, and for a large numbe= r of end-users. The most telling example was a MySQL server which we original= ly configured with 6.3 -- but it just collapsed under the full load when we = made it the back end for a popular web forums site. Exactly the same hardware= is in use now running 7.0 and not only is that DB server cruising along quite h= appily, but we've been able to add a bunch more web servers at the front of the s= ite. That's the most remarkable improvement I've seen, but it is not at all untypical. I can't speak to the model of needing to run hundreds of different applications on the same server -- about the closest thing I have to that= is my personal laptop (but only dozens of apps, rather than hundreds), an= d other than being vaguely aware that it seems to be working adequately, I'= ve never even tried to compare before and after performance.
