HFT Latency: Kernel Bypass Essential at Scale
Bryan Downing (@quantlabs) shared insights that kernel bypass becomes essential for HFT at scales of $100k+, prioritizing profit before advanced tweaks.
Kernel bypass allows direct access to network cards, reducing latency by avoiding OS kernel overhead. This is crucial when trading large volumes where even minor delays can impact profitability. For HFT firms, the cost of implementing kernel bypass solutions is justified by the potential gains from improved execution speed. These solutions often involve specialized hardware and software, requiring significant investment. Financial institutions are exploring FPGA-based solutions for kernel bypass to achieve ultra-low latency. FPGAs offer customizable hardware acceleration for specific trading algorithms.
