+## Performance Optimizations
+
+### Blockchain Performance
+
+#### **Block Production Tuning**
+```bash
+# Optimize block time for faster consensus (in /etc/aitbc/blockchain.env)
+block_time_seconds=2  # Default: 10, faster for testing
+
+# Enable/disable block production based on node role
+# aitbc1 (genesis): enable_block_production=true
+# aitbc (follower): enable_block_production=false
+```
+
+#### **Network Optimization**
+```bash
+# Optimize P2P settings
+p2p_bind_port=7070  # Standard port for P2P communication
+
+# Redis gossip optimization
+gossip_broadcast_url=redis://localhost:6379  # Local Redis for aitbc1
+gossip_broadcast_url=redis://10.1.223.40:6379  # Remote Redis for aitbc
+```
+
+#### **Database Performance**
+```bash
+# Ensure proper database permissions and location
+db_path=/var/lib/aitbc/data/ait-mainnet/chain.db
+chmod 755 /var/lib/aitbc/data
+chmod 644 /var/lib/aitbc/data/ait-mainnet/chain.db
+```
+
+### System Resource Optimization
+
+#### **Memory Management**
+```bash
+# Monitor memory usage
+systemctl status aitbc-blockchain-node --no-pager | grep Memory
+
+# Optimize Python memory usage (in systemd service)
+Environment=PYTHONOPTIMIZE=1
+Environment=PYTHONUNBUFFERED=1
+```
+
+#### **CPU Optimization**
+```bash
+# Set process affinity for better performance
+cpuset=/opt/aitbc/systemd/cpuset.conf
+echo "CPUAffinity=0-3" > /opt/aitbc/systemd/cpuset.conf
+```
+
+### Monitoring and Metrics
+
+#### **Real-time Monitoring**
+```bash
+# Monitor blockchain height in real-time
+watch -n 2 'curl -s http://localhost:8006/rpc/head | jq .height'
+
+# Monitor service status
+watch -n 5 'systemctl status aitbc-blockchain-* --no-pager'
+
+# Monitor resource usage
+watch -n 5 'ps aux | grep python | grep aitbc'
+```
+
+#### **Performance Metrics**
+```bash
+# Check block production rate
+curl -s http://localhost:8006/rpc/info | jq '.genesis_params.block_time_seconds'
+
+# Monitor transaction pool
+curl -s http://localhost:8006/rpc/mempool | jq .
+
+# Check network sync status
+curl -s http://localhost:8006/rpc/syncStatus | jq .
+```
+
 ## Troubleshooting
 
+### Common Issues and Solutions
+
+#### **Systemd Service Failures**
+```bash
+# Check service status and logs
+systemctl status aitbc-blockchain-*.service --no-pager
+journalctl -u aitbc-blockchain-node.service -n 10 --no-pager
+
+# Fix environment file issues
+find /etc/systemd/system/aitbc-blockchain-*.service.d/ -name "*.conf" -exec grep -l "EnvironmentFile" {} \;
+find /etc/systemd/system/aitbc-blockchain-*.service.d/ -name "*.conf" -exec sed -i 's|EnvironmentFile=/opt/aitbc/.env|EnvironmentFile=/etc/aitbc/blockchain.env|g' {} \;
+
+# Fix virtual environment paths in overrides
+find /etc/systemd/system/aitbc-blockchain-*.service.d/ -name "override.conf" -exec sed -i 's|/opt/aitbc/apps/blockchain-node/.venv/bin/python3|/opt/aitbc/venv/bin/python3|g' {} \;
+
+# Reload and restart
+systemctl daemon-reload
+systemctl restart aitbc-blockchain-node aitbc-blockchain-rpc
+```
+
+#### **RPC Service Issues**
+```bash
+# Check if RPC is accessible
+curl -s http://localhost:8006/rpc/head | jq .
+
+# Manual RPC start for debugging
+cd /opt/aitbc/apps/blockchain-node
+PYTHONPATH=/opt/aitbc/apps/blockchain-node/src:/opt/aitbc/apps/blockchain-node/scripts \
+  /opt/aitbc/venv/bin/python -m uvicorn aitbc_chain.app:app --host 0.0.0.0 --port 8006
+```
+
+#### **Keystore Issues**
+```bash
+# Create keystore password file
+echo 'aitbc123' > /var/lib/aitbc/keystore/.password
+chmod 600 /var/lib/aitbc/keystore/.password
+
+# Check keystore permissions
+ls -la /var/lib/aitbc/keystore/
+```
+
+#### **Sync Issues**
+```bash
+# Check network connectivity between nodes
+ping 10.1.223.40  # aitbc1 from aitbc
+ping 10.1.223.93  # aitbc from aitbc1
+
+# Check Redis connectivity
+redis-cli -h 10.1.223.40 ping
+
+# Compare blockchain heights
+curl -s http://localhost:8006/rpc/head | jq .height
+ssh aitbc 'curl -s http://localhost:8006/rpc/head | jq .height'
+```
+
+### General Troubleshooting
+
 - **Services won't start**: Check `/var/log/aitbc/` for service logs
 - **Sync issues**: Verify Redis connectivity between nodes
 - **Transaction failures**: Check wallet nonce and balance
