Koala Lib server crashes on startup – what to do?

Server lagging with Koala Lib – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Koala Lib consumes the most tick time.

With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
