Introduction

Game server performance is a critical factor that directly affects player experience. High latency, low tick rate, and insufficient resource management can cause players to leave your server. This guide covers CPU, RAM, network, and kernel-level optimizations for your game server on REXE VDS.

CPU Optimization

CPU Governor Setting

By default, Linux dynamically adjusts CPU frequency. For game servers, fixed high frequency is recommended:

hljs bash
# Check current governor
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

# Switch to performance mode
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

# Make persistent
sudo apt install cpufrequtils -y
echo 'GOVERNOR="performance"' | sudo tee /etc/default/cpufrequtils
sudo systemctl restart cpufrequtils

CPU Affinity (taskset)

Bind your game server to specific CPU cores for better performance:

hljs bash
# Bind server to cores 0 and 1
taskset -c 0,1 ./server_binary

# Bind a running process
taskset -cp 0,1 $(pidof server_binary)

CPU Isolation

Isolate specific cores for the game server using kernel parameters:

hljs bash
sudo nano /etc/default/grub
# Add to GRUB_CMDLINE_LINUX_DEFAULT:
# isolcpus=2,3 nohz_full=2,3 rcu_nocbs=2,3
sudo update-grub
sudo reboot

RAM Optimization

Swap Settings

Minimize swap usage for game servers:

hljs bash
# Check current swappiness
cat /proc/sys/vm/swappiness

# Lower swappiness (default 60)
echo 'vm.swappiness=10' | sudo tee -a /etc/sysctl.conf

# Dirty page settings
echo 'vm.dirty_ratio=15' | sudo tee -a /etc/sysctl.conf
echo 'vm.dirty_background_ratio=5' | sudo tee -a /etc/sysctl.conf

sudo sysctl -p

Huge Pages

Reduce TLB misses using huge pages:

hljs bash
# Set huge pages (2MB pages, 2048 count = 4GB)
echo 'vm.nr_hugepages=2048' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

# Verify
cat /proc/meminfo | grep HugePages

OOM Killer Protection

Protect the game server process from OOM killer:

hljs bash
echo -17 > /proc/$(pidof server_binary)/oom_adj

Tick Rate Optimization

What is Tick Rate?

Tick rate determines how many times per second the server updates the game state. Higher tick rate provides smoother gameplay but requires more CPU and bandwidth.

GameDefault Tick RateRecommended
CS264128
Minecraft2020
Rust3030
FiveM3060
V Rising3030-60

Adjusting Tick Rate

hljs bash
# CS2 with 128 tick
./cs2 -dedicated -tickrate 128

# FiveM (server.cfg)
sv_maxclients 64
set sv_enforceGameBuild 3095

Network Optimization

Kernel Network Parameters

hljs bash
sudo nano /etc/sysctl.conf
hljs ini
# UDP Buffer sizes
net.core.rmem_max=26214400
net.core.wmem_max=26214400
net.core.rmem_default=1048576
net.core.wmem_default=1048576

# Network queue size
net.core.netdev_max_backlog=65536
net.core.somaxconn=65535

# TCP optimization
net.ipv4.tcp_rmem=4096 87380 26214400
net.ipv4.tcp_wmem=4096 65536 26214400
net.ipv4.tcp_max_syn_backlog=65536
net.ipv4.tcp_tw_reuse=1
net.ipv4.tcp_fin_timeout=15

# UDP optimization
net.ipv4.udp_rmem_min=8192
net.ipv4.udp_wmem_min=8192

# Connection tracking
net.netfilter.nf_conntrack_max=1048576
hljs bash
sudo sysctl -p

Network Interface Optimization

hljs bash
# Increase ring buffer size
sudo ethtool -G eth0 rx 4096 tx 4096

# Interrupt coalescing
sudo ethtool -C eth0 rx-usecs 50 tx-usecs 50

Kernel Tuning

I/O Scheduler

Choose the appropriate I/O scheduler for game servers:

hljs bash
# Check current scheduler
cat /sys/block/sda/queue/scheduler

# For NVMe, none (noop) is recommended
echo none | sudo tee /sys/block/nvme0n1/queue/scheduler

# For SSD, mq-deadline is recommended
echo mq-deadline | sudo tee /sys/block/sda/queue/scheduler

File Descriptor Limits

hljs bash
sudo nano /etc/security/limits.conf
hljs ini
steam soft nofile 1000000
steam hard nofile 1000000
steam soft nproc 65535
steam hard nproc 65535

Monitoring Tools

Performance Monitoring

hljs bash
# CPU and RAM usage
htop

# Disk I/O monitoring
sudo iotop -o

# Network connections
ss -tuln

# Network traffic
sudo iftop -i eth0

# Detailed process monitoring
pidstat -p $(pidof server_binary) 1

Latency Testing

hljs bash
# Test server latency
ping -c 100 SERVER_IP

# Detailed path analysis with MTR
mtr --report SERVER_IP

Automatic Optimization Script

hljs bash
nano ~/optimize_gameserver.sh
hljs bash
#!/bin/bash
echo "=== Game Server Optimization ==="
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor 2>/dev/null
sudo sysctl -w vm.swappiness=10
sudo sysctl -w net.core.rmem_max=26214400
sudo sysctl -w net.core.wmem_max=26214400
sudo sysctl -w net.core.netdev_max_backlog=65536
ulimit -n 1000000
echo "Optimization complete."
hljs bash
chmod +x ~/optimize_gameserver.sh

Conclusion

Game server optimization through CPU, RAM, network, and kernel-level improvements provides significant performance gains. With regular monitoring and proper configuration, you can deliver a low-latency, smooth gaming experience. REXE VDS high-performance hardware and Path.net DDoS protection ensure optimal server performance.

Häufig gestellte Fragen

Was ist die Tick-Rate und warum ist sie wichtig?

Die Tick-Rate bestimmt, wie oft pro Sekunde der Server den Spielzustand aktualisiert. Höhere Tick-Rate bietet flüssigeres Gameplay, erfordert aber mehr CPU und Bandbreite.

Wie viel Unterschied macht der Performance-CPU-Governor?

Der Performance-Modus hält die CPU auf maximaler Frequenz. Dies kann 10-20% Leistungsverbesserung für Spielserver bieten.

Warum sollte ich den Swappiness-Wert senken?

Niedrigere Swappiness stellt sicher, dass RAM physischen Speicher statt Swap verwendet. Swap-Nutzung erhöht die Latenz.

Ist es sicher, die Netzwerk-Puffergrößen zu erhöhen?

Ja, aber passen Sie sie an Ihren Server-RAM an. Größere Puffer verwenden mehr RAM, verbessern aber die Netzwerkleistung.

Welcher I/O-Scheduler ist am besten für Spielserver?

Für NVMe-Laufwerke wird 'none' (noop) empfohlen. Für SSDs wird 'mq-deadline' empfohlen.
