CPU isolation and efficient system management are critical for any application which requires low-latency and high-performance computing. These measures are especially important for high-frequency trading systems, where split-second decisions on buying and selling stocks must be made. To achieve this level of performance, such systems require dedicated CPU cores that are free from interruptions by other processes, together with wider system tuning.
In modern production environments, there are numerous hardware and software hooks that can be adjusted to improve latency and throughput. However, finding the optimal settings for a system can be challenging as it requires navigating a multidimensional search space. To accomplish this efficiently, it is necessary to understand the tuning landscape and to use tools and strategies that facilitate effective changes.
