apache (httpd) on FC1/i386 vs FC2/x86_64: 3-8 times as much memory consumption?

Actually, I don't see RSS numbers particularly different between i686 
and x86_64.

For a server under ab load for a static page, I get an RSS of ~10.5Mb on
amd64, and ~9.5Mb on i686, which seems like a reasonable difference.
This is comparing like for like on RHEL3 U3, I don't have a Hammer box
running FC2 to compare.

You are comparing active servers not idle ones, right?  RSS of an idle
server is not interesting since it may be half swapped out.
