I actually was not thinking about the newer LDAP version.

The only LDAP stuff is looking up the home directory. Button used to be
hovering around load 2+ (I thought higher, but the graphs do not show
that). My guess is that because of that service being moved, button
can allocate more time to MySQL.

Strangely, the load on label even with openldap is much less than it
used to be on button. Maybe because of the incomplete config mentioned
by ninja.

Agreed; I do not want anything else on box. Further, even box does not
meet the minimum requirements for Bugzilla 3.0.
