It's a very complex workflow (in comparison to other apps I've worked on). It is also an old inherited app that is doing A LOT per most requests.
We have cleaned it up dramatically and server performance gets better with every release. Like Will G., those numbers are for peak hours on a U.S. data center. During off hours, there is very little traffic but of course that means it is peak hours on one of the other data centers. .:.:.:.:.:.:.:.:.:.:.:.:.:.

It really boils down to what the server's actually doing for a given request, though, and most CF applications I've seen are doing a LOT of work per request. In many cases, this is because the application isn't designed or implemented well, but in many other cases it's simply because the application workflow is complex. The application I mentioned earlier in the thread, VOANews (http://www.voanews.com/) is one of the top 15-20 news sites in the world - not especially popular in the US, but very popular elsewhere in the world. It runs on a fairly small number of servers (more than one but far less than any of the other sites called out in this thread by name). Hundreds of new articles are posted throughout the day, but everything gets cached and so the amount of work per request tends to be fairly low for most requests (readers) while extremely high for the publishing workflow requests. In this regard, it's not typical of most CF applications really. One other thing worth noting; the thread was spawned by cbo.gov being unavailable. Well, I can tell you from firsthand experience that the government does not, by and large, spend a lot of money on servers compared to the private sector. I've visited some agencies where the web server might as well have been powered by a hamster in a wheel. There are exceptions to this, but most government agencies don't have an operational crisis when their web server goes down - they just bring it up again and move on.
