Walk around for 2–3 minutes. Observe if the terrain generation is fast or if you experience "stuttering."
Eaglercraft is a fan-made, open-source port of Minecraft (specifically based on older, highly stable versions like Java Edition 1.5.2 and 1.8.8) rewritten to run on JavaScript and WebGL. Because it runs entirely within a standard web browser, it requires no launcher, no premium account, and no heavy hardware utilization. eaglercraft singleplayer test

The term "test" in the keyword implies performance verification. Here is how to benchmark Eaglercraft Singleplayer:
In singleplayer, your CPU must calculate terrain generation algorithms on the fly. During a test, increasing the render distance beyond 8 chunks usually reveals the limitations of browser-based Java-to-JavaScript compilation. Players look for frame rate drops (FPS stuttering) during rapid world exploration to evaluate how efficiently the game handles garbage collection. 2. Local Storage and IndexedDB
