The derailed_benchmarks gem is a suite of very useful tools for all kinds of performance work, primarily aimed at Rails apps. For finding leaks, we want to look at perf:mem_over_time, perf:objects, and perf:heap_diff. - Source: dev.to / over 1 year ago
If you're curious, attach VisualVM and watch the RAM usage graph. You'll notice that Java performs garbage collections long before reaching allocating the maximum amount of RAM allocated, and you can't even feel any performance issue in-game. Source: 11 months ago
Hangs and deadlocks are significantly harder to debug. A first step is taking a thread dump so you can see what each thread in the JVM is currently trying to do. I like VisualVM for this, you can also use the command-line tools jps -l (to list all Java PIDs) and jstack for taking a thread dump. Source: 11 months ago
The Java VisualVM project is an advanced dashboard for Memory and CPU monitoring. It features advanced resource visualization, as well as process and thread utilization. - Source: dev.to / 12 months ago
This sounds like a server thread freeze/deadlock/crash or something. I think I would start debugging this using a tool like VisualVM; attach it to the game, wait for the hang, take a thread dump, and check what the server thread is up to. Source: about 1 year ago
Just wanted to chip in to say that /u/UtilFunction is correct. The proper way to measure memory consumption of any Java application independent of which garbage collector is used is to perform a heap dump (which automatically forces a complete garbage collection). I like to use VisualVM for that. Source: about 1 year ago
