Performance & Scaling Guide¶

Optimize TINAA for enterprise-scale testing operations.

Scaling Architecture¶

Horizontal Scaling¶

# kubernetes deployment
apiVersion: apps/v1
kind: Deployment
metadata:
  name: tinaa-workers
spec:
  replicas: 10
  template:
    spec:
      containers:
      - name: tinaa
        resources:
          requests:
            memory: "2Gi"
            cpu: "1000m"

Vertical Scaling¶

Recommended specifications by workload: - Small (< 100 tests/day): 2 CPU, 4GB RAM - Medium (100-1000 tests/day): 4 CPU, 8GB RAM - Large (> 1000 tests/day): 8+ CPU, 16GB+ RAM

Performance Optimization¶

Test Execution Optimization¶

// Parallel execution configuration
module.exports = {
  workers: process.env.CPU_COUNT || 4,
  maxWorkers: 16,
  workerIdleMemoryLimit: '512MB'
};

Browser Management¶

// Reuse browser contexts
const browserPool = {
  maxInstances: 10,
  reuseExisting: true,
  launchOptions: {
    args: ['--disable-dev-shm-usage']
  }
};

Load Distribution¶

Queue-Based Architecture¶

// Redis queue configuration
const queue = {
  redis: {
    host: 'redis-cluster.internal',
    port: 6379,
    maxRetriesPerRequest: 3
  },
  concurrency: 20
};

Geographic Distribution¶

Deploy across regions: - US-East: Primary - EU-West: Secondary - APAC: Tertiary

Caching Strategies¶

Test Result Caching¶

const cache = {
  provider: 'redis',
  ttl: 3600, // 1 hour
  keyPrefix: 'tinaa:results:'
};

Static Asset Caching¶

CDN integration
Browser caching
Proxy caching

Monitoring & Metrics¶

Key Performance Indicators¶

Test Execution Time
Average: < 30 seconds
P95: < 2 minutes
P99: < 5 minutes
Resource Utilization
CPU: < 80%
Memory: < 75%
Disk I/O: < 60%

Monitoring Stack¶

monitoring:
  metrics: prometheus
  logging: elasticsearch
  tracing: jaeger
  alerting: pagerduty

Database Optimization¶

PostgreSQL Tuning¶

-- Optimize for read-heavy workload
ALTER SYSTEM SET shared_buffers = '4GB';
ALTER SYSTEM SET effective_cache_size = '12GB';
ALTER SYSTEM SET work_mem = '256MB';

Connection Pooling¶

const pool = {
  max: 20,
  min: 5,
  idle: 10000,
  acquire: 30000
};

Cost Optimization¶

Resource Management¶

Auto-scaling policies
Spot instance usage
Reserved capacity planning
Idle resource termination
