You can have multiple-threads in a single process. I couldn't find the
second reference and I don't know if it's a multi-threaded server but their
claims may not be in conflict if that is the case.

Are you saying the benchmark relies on access checks at each level and that
they do that very well while Apache doesn't?

I remember plans to improve that in Apache, did they ever come to anything?
The good thing about a published benchmark suite is we can see where Apache
has problems and fix them, nothing like a challenge :-)

Elsevier seems to be only 4 or 5 hops from, probably a 
256K line through but the server-push animation is *VERY* impressive. Several
frames a second would be my guess. (See the Zeus sites list or the
features link). I don't think Apache can do that across our ethernet :-(
