what does the overall workload on the system look like when this is so
slow? taking over a minute to do 1820 iterations of a 3138 row index
scan seems way out of bounds for anything other than a very heavily
overloaded server.

is this running on a virtual machine where there are other virtual
servers contending for the same resources ?
