System warmup techniques
System warmup is a critical process in high-performance systems that aims to prepare the system for optimal performance. It involves tasks designed to ensure that both the CPU and memory are ready to handle operations at the lowest possible latency from the start. This section will explore the importance of system warmup, discuss strategies for effective warmup that focus on priming CPU and memory, and look at practical case studies from the HFT sector to illustrate the impact of well-designed warmup routines.
Understanding the importance of warmup in low-latency systems
Understanding the importance of warmup in low-latency systems is crucial, particularly in fields such as HFT, where microseconds can significantly impact outcomes. Warmup procedures are designed to prime a system’s hotpath, the critical execution path that is most frequently used during operation. These procedures ensure that the necessary code and data are loaded into the CPU...
