BUT if you want a real smooth experience for a few players, start at 4 GB. That's why most hosts don't offer servers smaller than 2 GB.Can too much RAM lag Minecraft?
Yes, allocating too much RAM to Minecraft can cause lag spikes and performance issues, primarily due to Java's Garbage Collection (GC) having to clear larger chunks of memory at once, leading to noticeable pauses. While having enough RAM is good, excessive allocation makes GC pauses longer and more disruptive, creating lag, especially with memory leaks from mods. The solution is finding a "sweet spot," usually slightly above the game's actual need, not maxing it out.Is my Minecraft world too big, causing lag?
