Well, certainly adding authz to the mix adds quite a bit of processing
overhead -- ViewVC has to consult the authz configuration to discern the
readability of every path.  And log views are especially harsh, because that
means checking every path changed in a revision for every revision whose log
is being display.  Still, if you can help us by categorizing classes of
problems, we can start looking to see if the processing that's going on is
just par for the course or somehow excessively wasteful.  Is it as simple to
trigger as flipping the 'authorizer' configuration on and off?
