Performance Optimization

Maximize your TinyBox VPS performance and efficiency

Memory Optimization

Add Swap Space

# Create swap file (recommended: 1-2x RAM size)
fallocate -l 2G /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile

# Make permanent
echo '/swapfile none swap sw 0 0' >> /etc/fstab

# Optimize swap usage
echo 'vm.swappiness=10' >> /etc/sysctl.conf
echo 'vm.vfs_cache_pressure=50' >> /etc/sysctl.conf

# Apply changes
sysctl -p

Memory Monitoring

# Check memory usage
free -h

# Show top memory consumers
ps aux --sort=-%mem | head -10

# Monitor memory in real-time
watch -n 2 free -h

# Clear memory cache (if needed)
sync && echo 3 > /proc/sys/vm/drop_caches

CPU & Process Optimization

Process Management

# Find CPU-heavy processes
top -o %CPU

# Kill resource-hungry process
kill -15 PID_NUMBER

# Set process priority (nice)
nice -n 10 command
renice 10 -p PID_NUMBER

Load Monitoring

# Check current load
uptime

# Monitor load in real-time
vmstat 1

# I/O wait monitoring
iostat -x 1

Healthy Load Averages

TINY 1.0 VPS (1 CPU):

• Good: < 0.7
• Fair: 0.7 - 1.0
• High: > 1.0

TINY 2.1 VPS (2 CPU):

• Good: < 1.4
• Fair: 1.4 - 2.0
• High: > 2.0

Disk I/O Optimization

Disk Usage Analysis

# Check disk usage
df -h

# Find largest directories
du -sh /* 2>/dev/null | sort -hr | head -10

# Find large files
find / -type f -size +100M 2>/dev/null | head -20

# Analyze specific directory
du -ah /var/log | sort -hr | head -10

Log Management

# Clean system logs
journalctl --vacuum-size=100M
journalctl --vacuum-time=30d

# Clean old logs
find /var/log -name "*.log" -mtime +30 -delete
find /var/log -name "*.gz" -mtime +30 -delete

# Set up log rotation
nano /etc/logrotate.conf

Application-Specific Optimizations

Web Server (Nginx)

# Optimize nginx.conf
worker_processes auto;
worker_connections 1024;
keepalive_timeout 30;

# Enable compression
gzip on;
gzip_min_length 1000;
gzip_types text/plain application/json;

# Enable caching
location ~* \.(jpg|jpeg|png|gif|css|js)$ {
    expires 1y;
    add_header Cache-Control "public, immutable";
}

Database (MySQL)

# Optimize my.cnf for limited RAM
[mysqld]
innodb_buffer_pool_size = 256M
max_connections = 30
query_cache_size = 32M
tmp_table_size = 32M
table_open_cache = 64
innodb_log_file_size = 32M

PHP Optimization

# Optimize php.ini
memory_limit = 256M
max_execution_time = 30
max_input_vars = 3000
opcache.enable = 1
opcache.memory_consumption = 64

Node.js with PM2

# PM2 ecosystem.config.js
module.exports = {
  apps: [{
    name: 'app',
    script: 'app.js',
    instances: 'max',
    max_memory_restart: '256M',
    node_args: '--max-old-space-size=256'
  }]
};

💡 Performance Tips

• Run the performance check weekly
• Monitor during peak usage times
• Set up automated alerts for high usage

• Keep swap usage below 50%
• Restart services weekly
• Update software regularly
