# How to run a Minecraft Server that doesn't suck by Max!
## Why should you listen to me?
### Head of the Minecraft Club on campus
### Playing Minecraft most of my life
## 5 Main aspects of running a Minecraft server
### Hardware
#### Two methods
##### Pay someone else to host it
###### A good server would cost ~100-300/month
##### or host it yourself
###### Initial cost a lot higher
###### Operating cost much lower (basically just electricity)
###### MC Club's desktop cost $830 and can run into the future
#### CPU
##### Go for big single-core performance CPUs
##### Minecraft is singlethreaded
###### Java moment?
###### More like Minecraft moment, Java supports multithreading but they just didn't support it because it's more difficult
##### Memory
###### MC Club went with 32GB/ram
##### Storage/Networking
###### low-latency storage
###### NVME is best, SATA SSD is fine
###### just avoid HDDs
###### Worlds aren't very big (MC club is currently at 50GB)
###### Try to have low latency and a stable network so players don't hate you
### Software
#### Considering either Windows 11 or Windows Server 2025
#### Of course, went with Linux (Debian)
#### Server options
##### Vanilla
##### Fabric
###### Mods usually try to avoid impacting vanilla game mechanics
##### Paper
###### Server admins tend to like it
###### Power players, not so much
###### Unavoidably breaks some game mechanics players rely on
###### However, grants access to a huge library of Spigot plugins and improves performance a ton even on crappy hardware
##### Using a different JVM to increase performance
###### MC Club is using Azul Zing because it benchmarked the best
##### Improve garbage collection via launch arguments
#### Can setup SRV record for different servers on the same host so users don't need to specify a different port
### Configuration
#### server.properties is the main config file
##### All your standard settings, and....
##### Can configure server to auto-freeze when server is inactive
##### And can specify region chunk compression algorithm (more on this later)
#### Mods
##### NoChatReports
###### removes users being able to submit other user's messages back to Microsoft and potentially get them permanently banned from Multiplayer
##### GeyserMC + Floodgate
###### Allow bedrock players to join a Java server
##### Simple Voice Chat
###### In-game proximity voice chat
###### Improves social experience
##### Distant Horizens
###### Allows the server to send less-detailed chunks to the client, so it allows the client to see super far without a massive performance penalty
####### However, eats a lot of storage (~70GB)
#### Other Stuff
##### Chat bridge to mirror Minecraft chat to another chat (usually a Discord server)
##### Auto whitelisting
###### You don't want to have a public minecraft server, in case someone port scans the entire IPv4 space and finds+griefs your world
###### Worked pretty good so far, one incident in 2 months
### Optimization
#### Lag
##### Every 1/20th of a second game 'ticks' entire world (IE updates everything)
##### Ticks must be <50ms or eating is noticable, you get teleported back, and a lot of other annoying things
##### Spawning/Entities is very laggy
##### Block updates usually not so much, barring massive redstone contraptions
##### World generation can be a major lag producer if you are generating chunks
##### Easiest fix is decreasing simulation distance
##### You can also pregenerate large parts of the world before people first join
##### Change region file compression algorithm
###### Switch from DEFLATE to LZ4 (faster), prevents lag spikes during autosave
###### World files will be ~20-30% larger though
##### Optimization mods
###### All are only performance-based and do not change how the game operates
###### Lithium: General optimizations
###### ScalableLux: better lighting engine
###### Krypton improves network performance
###### Very Many Players: caching and other technology to improve performance with very high player counts
###### OptimizedTNT: nice for players that allegedly build TNT-orbital-strike-cannons that otherwise would crash the server
####### In fairness, this should probably be expected considering Tech is an engineering school
##### In-game lag reduction
###### Avoid high entity counts in small areas
####### Animal pens are a frequent offender
####### MC club server had one person with a chicken pen with 1000+ chickens in it that was responsible for ~80% of the in-game lag
####### Apparently Chickens used to be immune to entity cramming damage.
####### Spark is essentially a java profiler that shows what methods Minecraft spends most of its CPU time on
### Management
#### As an admin, be transparent with the playerbase
#### Allow people to talk about changes before changing things
#### Don't abuse admin perms to benifit yourself, players typically don't like this
##### Yaoi bribed have been alleged to work for some admins in return for Elytras when servers are out
#### Keep rules short and sweet, otherwise no one will read them
##### Outline what rules and enviornment you want for the server
##### Swift bans for people openly breaking rules (e.g. x-ray)
#### Minecraft Club actually disabled the Nether for the first day of the server to allow people to prepare
### And most importantly of all, have fun!
## Live demo!
### Can configure sudo to not prompt for a password when logged in via ssh private key
### World backup every hour, keeps for last 6 hours
#### `cat banned-players.json`
##### that one person who was obviously using x-ray
##### for shame!
#### Live chat preview
##### "[Server] i am watching you"
##### "<Sting1> D: 1984"
#### Get to see the (in)famous pen of 1000+ chickens that's eating 80% of each server tick
### That was the server!
### Obligatory plug for Minecraft Club Discord Server
#### Minecraft club is also hosting a world for East Hall
##### Paid $300 for indefinite hosting
##### Remains to be seen if East Hall Accociation will still exist as an entity after the building inevitably collapses
# After talk discussion
## MC Java technically does have multithreaded word generation, but it's very poorly multithreaded so not much better than single-threaded
## Bedrock has some advantages in this regard
### "not-java" brings a lot of performance advantages
## Good transparency on the part of 2B2T
### page for all custom mods/software
### 2B2T uses Folia (regioned-threading), from the PaperMC project
### Breaks even more than regular Paper
## For most servers, an admin would probably not want Paper or Folia
