# Performance metrics table
| Component | Response Time | Throughput | Availability |
|-----------|---------------|------------|--------------|
| Web Server|     45ms      |  1000 RPS  |    99.9%     |
| Database  |     12ms      |  5000 RPS  |    99.95%    |
| Cache     |      2ms      | 50000 RPS  |    99.99%    |

# Code example
```javascript
// API endpoint with caching
app.get('/api/users/:id', async (req, res) => {
  const cacheKey = `user:${req.params.id}`;

  // Check cache first
  const cached = await redis.get(cacheKey);
  if (cached) {
    return res.json(JSON.parse(cached));
  }

  // Fetch from database
  const user = await db.query('SELECT * FROM users WHERE id = $1',
                              [req.params.id]);

  // Cache result
  await redis.setex(cacheKey, 3600, JSON.stringify(user));

  res.json(user);
});
```
