That particular table is frequently very large and thus "not fast".  Can
you try something for me: query it again using a large timeout ("-t 120
-r 0" will let it try for 120 seconds to answer and will only query it
once).

I suspect that the issue may be the agent is still trying to answer the
questions asked and it's taking too long.  Then another (retry) query
gets to it, and after it finally answers the first it starts thinking
about the second.

If you look at 'top' output or another similar tool, I bet you'll find
the agent is simply thinking.
