That answer is way too flippant.  In particular it doesn't explain your
repeated 80sec queries --- you should have enough memory in that thing
to be caching a fair amount of your data.

I'm wondering about some transaction taking exclusive lock on the table
and sitting on it for a minute or so, and also about network problems
delaying transmission of data to the client.
