Reminder: Always enable GC logging in production If you run a production server, and you don’t have GC logs enabled, DO IT NOW. Really, it could save your ass. It is unnoticeable in terms of performance impact, and is invaluable if you need to diagnose some performance issue. It was a bit of a mess with HotSpot many years ago, since log rotation was not available. But now it’s been added for quite a long time, there is no excuse anymore.
