2. Traffic Simulation - Summary
• Scenario
– 25 rooms x 16 players = 400 CCU
– 2 x 50 bytes reliable / s, 10 x 50 bytes unreliable / s
• Server: Quad-Core, 8GB RAM, Win7 x64
– In: 4,500 msg/s (1,2 MB/s)
– Out: 65,000 msg/s (7.5 MB/s)
– CPU: ~30%
– NIC (100Mbit): 80% saturated
– Client RTT: ~40ms

3. Cost Estimate
• Traffic (400CCU, per month)
– Traffic = 8MB/s * 60 * 60 * 24 * 30 * 50% = ~10 TB
• Cost
– Server Cost (HW, OS & traffic): $400
– Cost per CCU ~= $400/400CCU = $1
– 400 CCU ~= 4,000 DAU ~= 40,000 MAU
– Cost per MAU ~= 1 Cent
