Performance

Keep Contained Opolis (A Space Adventure)
running smooth

Big modpacks ask a lot of the server. A few simple steps keep Contained Opolis (A Space Adventure) stable for everyone, even during heavy exploration and automation.

Pre-generate the world

Run a chunk pre-generation before you play so the server is not building new chunks while people explore. This is the single biggest fix for lag spikes on Contained Opolis (A Space Adventure).

Allocate enough RAM

Give Contained Opolis (A Space Adventure) at least 8GB. Too little RAM causes stutters and crashes; our plans make it a one-click upgrade.

Use fast hardware

Modded Minecraft is single-thread heavy, so CPU clock speed matters. Every plan runs on high-clock AMD CPUs with NVMe storage by default.

Server was running Great...

Server was running Great.... until it wasn't. This was entirely my fault. I started up a Modded Minecraft server for me and some friends. They are all newish to the modded minecraft so they are pretty easy on the server. I, on the other hand, am well versed. So I went full on speed run to get as much materials as possible. Starting these massive farms so everybody could get enough of whatever materials they may or may not need. I did one too many and broke the server through a build up of entities.First thing I did was go to their Discord and started a support ticket. Not only were the responses rolling in with very minimal delay, they even looked over my crash logs and helped me diagnose the issues. Then gave me multiple choices, all while, on their own time, help optimise my server settings.

Game Host Bros 6 Months In...

I've been with Game Host Bros for about 6 months now. Game Host Bros offers affordable gaming servers in a variety of regions for a variety of games.For me, Game Host Bros has been both reliable and good hearted. The team is absolutely incredible with support being both fast and comprehensive, shoutout to Michael Longo an absolute champion. Multiple times I've decided to swap between a Minecraft server and a Vintage Story server and without issues, complications and/or extra charges I've been able to have these changes made.I plan to renew my one year subscription once it has expired. I highly recommend Game Host Bros as a provider. Very impressed and deeply satisfied.-Ryan Wheeler

Probably the best yet.

In 10 years of Minecraft hosting, this is by far the cheapest I've had. And you'd think, cheap means quality lacks right? WRONG. Doing research you can see the specs of the servers they use are the same. With additions in the checkout panel, a STRONG server running 20gbRAM - extra cores - extra memory, is +-$25 from this provider, whereas other providers would happily charge $60+. Support so far has been top tier, if your ticket takes time they offer live chats and a discord with some pretty helpful members and staff.10/10 for Minecraft, as I expand my network I will stay with them, and any game servers that may come in the future.
