Database Requirements

# PostgreSQL Configuration
shared_buffers = 256MB          # 25% of RAM
effective_cache_size = 1GB      # 50% of RAM
work_mem = 4MB                  # Per operation

Runtime Performance

// React Optimization
const MemoizedComponent = React.memo(MyComponent);
const CallbackRef = useCallback(() => {}, []);
const MemoValue = useMemo(() => computeExpensiveValue(a, b), [a, b]);

// Virtual Scrolling for Large Lists
import { FixedSizeList as List } from 'react-window';

class CacheManager {
  private cache = new Map();
  private maxSize = 1000;
  private ttl = 3600000; // 1 hour

  set(key: string, value: any, ttl?: number) {
    if (this.cache.size >= this.maxSize) {
      this.evictLRU();
    }

Troubleshooting Performance Issues

Common Performance Problems

High Memory Usage

Diagnosis:

# Check process memory
pm2 monit

# Check system memory
free -h

# Check for memory leaks
node -e "setInterval(() => { console.log(process.memoryUsage()) }, 1000)"

Solutions:

# Restart services
pm2 restart all

# Clear caches
redis-cli FLUSHALL

# Check for memory leaks in logs
journalctl -u pluggedin-app -f | grep -i memory

Slow Database Queries

Diagnosis:

-- Find slow queries
SELECT query, calls, total_time, mean_time
FROM pg_stat_statements
ORDER BY mean_time DESC
LIMIT 10;

-- Check table statistics
SELECT schemaname, tablename, n_tup_ins, n_tup_upd, n_tup_del, n_live_tup
FROM pg_stat_user_tables
ORDER BY n_live_tup DESC;

Solutions:

# Update statistics
ANALYZE VERBOSE pluggedin_db;

# Rebuild indexes
REINDEX INDEX CONCURRENTLY idx_servers_profile_uuid;

# Check for missing indexes
pg_stat_user_indexes

High CPU Usage

Diagnosis:

# Check CPU usage
top -p $(pgrep -f pluggedin)

# Check CPU per process
ps aux | grep pluggedin | grep -v grep

# Check system load
uptime

Solutions:

# Enable slow query logging
echo "log_min_duration_statement = 1000" >> postgresql.conf

# Check for expensive operations
EXPLAIN ANALYZE SELECT * FROM documents WHERE profile_uuid = 'uuid' ORDER BY created_at DESC;

Performance Best Practices

Development Phase

Code Optimization

# Use performance monitoring
npm install --save-dev @next/bundle-analyzer

# Enable source maps for debugging
SOURCEMAP=true npm run build

# Use tree shaking
npm run build -- --analyze

Database Design

-- Use appropriate data types
ALTER TABLE users ALTER COLUMN created_at TYPE TIMESTAMP;

-- Add constraints for performance
ALTER TABLE documents ADD CONSTRAINT check_source CHECK (source IN ('upload', 'ai_generated', 'api'));

-- Use partitioning for large tables
CREATE TABLE documents_y2024 PARTITION OF documents FOR VALUES FROM ('2024-01-01') TO ('2025-01-01');

Production Optimization

Resource Allocation

# Set appropriate limits
ulimit -n 65536
ulimit -u 4096

# Monitor resource usage
iotop -p $(pgrep -f pluggedin)

Regular Maintenance

# Daily cleanup
find /app/uploads -type f -mtime +30 -delete

# Weekly optimization
pnpm db:optimize

# Monthly analysis
pnpm performance:analyze
