Performance Tuning
Optimize Linux system performance.
System Monitoring
top / htop # Process monitoring
vmstat 1 # Memory statistics
iostat -x 1 # Disk I/O
sar -n DEV 1 # Network statistics
perf top # CPU profiling
Kernel Parameters
# /etc/sysctl.d/99-performance.conf
vm.swappiness = 10
net.core.somaxconn = 65535
net.ipv4.tcp_max_syn_backlog = 65535
fs.file-max = 2097152
vm.dirty_ratio = 40
vm.dirty_background_ratio = 10
File Descriptor Limits
# /etc/security/limits.conf
* soft nofile 65535
* hard nofile 65535
* soft nproc 65535
* hard nproc 65535
Disk I/O
# Change scheduler
echo noop > /sys/block/sda/queue/scheduler
# Enable trim for SSDs
fstrim -av
Network Tuning
# Increase buffers
sysctl -w net.core.rmem_max=134217728
sysctl -w net.core.wmem_max=134217728
Best Practices
- Profile before optimizing
- Change one parameter at a time
- Monitor impact of changes
- Document all tuning
