OK, thanks for the info, however see below

We got to the bottom of this, one particular queue had
privileges set such that Everyone could be an owner of
a ticket.  The QueryBuilder was attempting to populate
the Owner dropdown list with everyone who had emailed
RT (tens of thousands!)

Disabling this feature fixed this problem - QueryBuilder
now displays in under 3 seconds now.
