My takeaway is that starting the checkpoint process is really expensive - so I don't want to start it very frequently. And the only downside to longer intervals between checkpoints is a longer recovery time if the system crashes?
And additional disk space wasted in hold the write-ahead logs. You're moving in the right direction here, the less checkpoints the better as long as you can stand the recovery time. What you'll discover if you bump checkpoint_segments up high enough is that you have to lengthen the test run you're trying, because eventually you'll reach a point where there are none of them happening during some test runs.
