Performance Benchmarks

Tested Version: PicoLimbo v1.4.0+mc1.21.8

Summary

PicoLimbo demonstrates exceptional performance efficiency across different architectures, handling large numbers of concurrent Minecraft connections with minimal resource consumption. The benchmarks show that PicoLimbo can efficiently manage 1,000 concurrent idle players on both x86 and ARM platforms, using less than 11 MB of RAM and maintaining low CPU usage once connections stabilize.
