Surprising Lessons from Achieving Sub-Microsecond RT Latency

5 Surprising Lessons from Achieving Sub-Microsecond RT Latency When writing code for low-latency trading, many "well-known best practices" must be ignored—or even reversed. What works in theory often collapses in real-world performance. 1. Atomics Lie After extensive testing, the only atomic that remained in our code was
