Karl Wright commented on CONNECTORS-281:
----------------------------------------
During this time CPU is pretty much maxed out between the postgres activity and
the agents daemon. The agents daemon is the lion's share of that (75%).
It is possible that the cause is simply insufficient RAM, since I've only given
the agents daemon 128MB for the test. But the times per fetch seem too high
and too consistent to be due to garbage collection. But something is clearly
busy-waiting nonetheless.
A thread dump would be helpful.
