Latency is pervasive, the silent killer that sneaks and kills your performance. Present at every level of the stack, it leaves expensive resources tied up waiting. With a focus on the larger implication of networking on performance, Artur will provide an exploration in why things are slow — and why it is our responsibility to understand our stack so we can fix it. Based on the experience of building and running a CDN with servers around the world that have one mission, deliver data as fast as possible, I’ll take a whirlwind tour around some of the issues:

TCP — how it affects us
• Monitoring performance and latency
• Reasoning about performance data and expectations
• Cheating speed of light
• User perception
