[xcat-user] Severe performance problem in 2.12

[Jarrod J. <jjo...@le...>]

I haven't yet dug in to understand the intent, but:
    my $hierarchy_field = xCAT::TableUtils->get_site_attribute("hierarchicalattrs");

That line in Table.pm is causing tremendous slowdown, particularly around discovery.  When a process does not have XCATSITEVALS populated, this causes an unmanageable number of SQLQ queries.
