📋 Documentation Navigation: Main README | Quick Start | Deployment Guide | Performance API

Overview¶

SecureWatch implements enterprise-grade performance optimizations to achieve Splunk/Sentinel-like dashboard performance and handle large-scale SIEM operations. This guide documents the implemented optimizations and their impact.

Performance Optimizations Implemented¶

1. EventsTable Virtualization¶

Problem: Rendering 100K+ log entries in a table causes browser freezing and poor user experience.

Solution: TanStack Virtual row virtualization

Implementation Details¶

File: /frontend/components/explorer/EventsTable.tsx
Technology: @tanstack/react-virtual
Row Height: Fixed 80px for optimal performance
Overscan: 10 rows for smooth scrolling
Memory Usage: Only visible rows are rendered in DOM

Performance Metrics¶

Before: Browser freeze with 10K+ rows
After: Smooth scrolling with 100K+ rows
Memory Usage: 95% reduction in DOM nodes
Scroll Performance: 60fps smooth scrolling

Code Example¶const virtualizer = useVirtualizer({
  count: filteredData.length,
  getScrollElement: () => parentRef.current,
  estimateSize: () => ROW_HEIGHT,
  overscan: 10,
});

2. TimescaleDB Continuous Aggregates¶

Problem: Dashboard queries taking 5-10 seconds with growing data volumes.

Solution: Pre-computed materialized views with TimescaleDB continuous aggregates

Implementation Details¶

File: /infrastructure/database/continuous_aggregates.sql
Aggregates: 6 materialized views covering different time intervals
Refresh Policy: Automatic refresh every 1-5 minutes
Data Retention: Automatic cleanup of old aggregates

Implemented Aggregates¶

realtime_security_events (5-minute buckets)
- Real-time dashboard data
- Event counts, error rates, unique sources
- Refresh: Every 1 minute
hourly_security_metrics (1-hour buckets)
- Trend analysis and historical data
- Source-specific metrics
- Refresh: Every 5 minutes
daily_security_summary (daily buckets)
- Executive dashboards and reports
- Compliance metrics
- Refresh: Daily at midnight
source_health_metrics
- Source monitoring and health status
- Performance metrics per source
- Refresh: Every 2 minutes
alert_performance_metrics
- Alert analytics and performance
- False positive rates
- Refresh: Every 5 minutes
compliance_event_summary
- Compliance reporting (SOX, HIPAA, PCI-DSS)
- Audit trail summaries
- Refresh: Daily

Performance Metrics¶

Before: 5-10 second dashboard load times
After: Sub-second response times (< 200ms)
Query Reduction: 90% fewer database queries
Cache Hit Rate: 85-95% for dashboard widgets

Helper Views¶

-- Real-time current hour summary
CREATE VIEW current_hour_summary AS
SELECT * FROM realtime_security_events 
WHERE time_bucket >= date_trunc('hour', NOW());

-- Today's summary
CREATE VIEW today_summary AS
SELECT * FROM daily_security_summary 
WHERE date_bucket = CURRENT_DATE;

-- Source health overview
CREATE VIEW source_health_overview AS
SELECT * FROM source_health_metrics 
WHERE time_bucket >= NOW() - INTERVAL '1 hour';

3. Async Job Processing System¶

GET  /api/jobs/:id/status      // Get job status
GET  /api/jobs/:id/results     // Stream results
POST /api/jobs/:id/cancel      // Cancel running job
GET  /api/jobs/list            // List user jobs

4. Consolidated Analytics Engine Service¶

Problem: Generic /query endpoint too slow for dashboard widgets.

Solution: Consolidated analytics-engine service with optimized endpoints

Implementation Details¶

Service: /apps/analytics-engine/ (Port 4009) - Consolidated from analytics-api

Performance Metrics¶

Response Times: 50-200ms average
Cache Hit Rate: 85-95% depending on endpoint
Memory Usage: Efficient NodeCache with automatic cleanup
Rate Limiting: Prevents abuse and maintains performance

Caching Strategy¶

// Different TTL values based on data criticality
const cacheTTL = {
  'critical-alerts': 15,      // 15 seconds
  'total-events': 30,         // 30 seconds  
  'active-sources': 60,       // 1 minute
  'security-incidents': 120,  // 2 minutes

Cross-Architecture Concurrency Optimization¶

Overview¶

SecureWatch implements intelligent concurrency management to optimize build and development performance across different system architectures. The turbo build system automatically adjusts parallelism based on available CPU cores and memory constraints.

Architecture-Specific Concurrency Recommendations¶

ARM64 (Apple Silicon M1/M2/M3/M4)¶

Optimal Concurrency: CPU cores × 1.5
Mac mini M4 (10 cores): 15 concurrent tasks
MacBook Pro M3 Max (12 cores): 18 concurrent tasks
Memory Consideration: 16GB+ RAM recommended for full concurrency
Thermal Management: ARM64 efficiency allows sustained high concurrency

Configuration Example:

{
  "concurrency": 15,
  "globalEnv": ["NODE_ENV", "DATABASE_URL"],
  "globalDependencies": ["**/.env.*local"]
}

x86_64 (Intel/AMD)¶

Optimal Concurrency: CPU cores × 1.2-1.4
Intel i7-12700K (12 cores): 14-17 concurrent tasks
AMD Ryzen 9 5900X (12 cores): 14-17 concurrent tasks
Memory Consideration: 2GB RAM per concurrent task
Thermal Considerations: Monitor CPU temperatures under load

Configuration Example:

{
  "concurrency": 14,
  "globalEnv": ["NODE_ENV", "DATABASE_URL"],
  "globalDependencies": ["**/.env.*local"]
}

MIPS (Embedded Systems)¶

Optimal Concurrency: CPU cores × 0.8-1.0
MIPS64 (4 cores): 3-4 concurrent tasks
Memory Consideration: Limited RAM requires conservative settings
I/O Constraints: Storage speed often the bottleneck

Configuration Example:

{
  "concurrency": 4,
  "globalEnv": ["NODE_ENV"],
  "globalDependencies": ["package.json"]
}

ARM32 (Raspberry Pi)¶

Optimal Concurrency: CPU cores × 0.8
Raspberry Pi 4 (4 cores): 3 concurrent tasks
Memory Consideration: 4GB RAM maximum, conservative approach
Thermal Management: Passive cooling requires lower concurrency

Configuration Example:

{
  "concurrency": 3,
  "globalEnv": ["NODE_ENV"],
  "globalDependencies": ["package.json"]
}

Memory Considerations¶

Memory Per Concurrent Task¶

TypeScript Compilation: ~512MB per task
React/Next.js Build: ~1GB per task
Docker Operations: ~256MB per task
Testing: ~256MB per task

Memory Calculation Formula¶

# Calculate safe concurrency based on available memory
AVAILABLE_MEMORY_GB=$(free -g | awk 'NR==2{printf "%.1f", $7}')
SAFE_CONCURRENCY=$((${AVAILABLE_MEMORY_GB%.*} / 2))
echo "Recommended concurrency: $SAFE_CONCURRENCY"

Auto-Detection Scripts¶

  let multiplier;
  
  // Architecture-specific multipliers
  if (arch === 'arm64' && platform === 'darwin') {
    multiplier = 1.5; // Apple Silicon
  } else if (arch === 'x64') {
    multiplier = 1.3; // Intel/AMD
  } else if (arch.includes('mips')) {
    multiplier = 0.9; // MIPS embedded
  } else if (arch.includes('arm')) {
    multiplier = 0.8; // ARM32
  } else {
    multiplier = 1.0; // Conservative default
  }
  
  const concurrency = Math.max(1, Math.floor(cpuCores * multiplier));
  
  // Memory constraint check
  const memoryLimitedConcurrency = Math.floor(totalMemory / 2);
  
  return Math.min(concurrency, memoryLimitedConcurrency);
}

function updateTurboConfig() {
  const turboConfigPath = path.join(process.cwd(), 'turbo.json');
  
  if (!fs.existsSync(turboConfigPath)) {
    console.error('turbo.json not found');
    return;
  }
  
  const config = JSON.parse(fs.readFileSync(turboConfigPath, 'utf8'));
  const optimalConcurrency = detectOptimalConcurrency();
  
  config.concurrency = optimalConcurrency;
  
  fs.writeFileSync(turboConfigPath, JSON.stringify(config, null, 2));
  
  console.log(`Architecture: ${os.arch()}-${os.platform()}`);
  console.log(`CPU cores: ${os.cpus().length}`);
  console.log(`Total memory: ${(os.totalmem() / (1024 * 1024 * 1024)).toFixed(1)}GB`);
  console.log(`Optimal concurrency: ${optimalConcurrency}`);
  console.log('Updated turbo.json successfully');
}

if (require.main === module) {
  updateTurboConfig();
}

module.exports = { detectOptimalConcurrency, updateTurboConfig };

sudo powermetrics -n 1 -s cpu_power | grep "CPU die temperature"

# Reduce concurrency if > 80°C
jq '.concurrency = (.concurrency * 0.8 | floor)' turbo.json > turbo.json.tmp && mv turbo.json.tmp turbo.json

I/O Bottlenecks

# Monitor disk usage
iostat -x 1

# Use faster storage or reduce concurrent disk operations

Network Resource Limits

# Limit network-heavy tasks
