Google's Performance Playbook: Writing Ridiculously Fast Code

Debunking Optimization Myths

• 💡 The biggest myth is to optimize everything; instead, focus on the critical 3% of your code that represents true bottlenecks.
• 🔍 Your job is to become a detective to find these specific performance-limiting areas.

Understanding Machine Latency

• 🧠 Build an intuition for performance by understanding the machine's native language: nanoseconds.
• 🚀 Recognize the immense speed difference, from half a nanosecond for L1 cache access to 150 million nanoseconds for a network roundtrip.
• 📊 Use a
