It's much worse than that though because this isn't a case of measure throughput with, then without and see which is best. Rather, your application is sailing toward a submerged iceberg that when it hits (could be next week) will stall your process, and potentially the entire box, for 60 seconds.

And it doesn't print a message like "yeah I stalled your box for the last 60 seconds in order to shuffle deckchairs around, sorry" in syslog.

So you pull your hair out trying to figure out why your nice stable service all of a sudden sets off Nagios at 2am for no obvious reason, every week or two.
