[horde] Hardware/config recommendations for large rollout

That is up to whoever built your httpd server.  As Chuck said:

If you are careful compiling/building apache, you can get it down around
5-10 MB range easily (mine I think is around 6-8 MB).

It may be normal for vendor supplied servers, since they tend to include
as much as possible into the static server image.

2000+ concurrent connections is huge.  It will take some serious
hardware.  I'd recommend multiple servers with some kind of load
balancing or load sharing.

My University handles a large service base by putting lots of servers
behind a load balancer.  It's not so important what kind of machines
you use, as long as you use enough. The more powerful the machines,
the fewer you need, and vise-versa.
