Interesting timing. I play with a few friends on a modded 1.7.10 server and we’ve decided to restart with 1.16 due to the lag having become untenable. We run it on an i7 machine at my house dedicated to it, so it’s not a hardware issue. Like clockwork the server would freeze for about 5s about every 30s. Using opus our best guess is that it’s unloading chunks and the GC is happening. We’re going to run 1.16 now which I hope has some performance enhancements and so that we can use more modern Java 16 runtime with its nicer GC systems. I’m also hoping that Minecraft has at least since moved chunk generation off the main thread since there was no good reason for world exploration slowing down things like it did. I also built a JavaScript redstone simulator website and I’m curious how you will handle that and other block updates at server boundaries.
