Bare-Metal Kernel Tuning for Low-Latency Systems
Deterministic performance environment for trading and real-time analytics, achieving ultra-low latency via NUMA-aware allocation and network stack tuning.
The Challenge
High-frequency trading systems required sub-microsecond latency but were limited by operating system overhead and network stack inefficiencies. Standard Linux kernels introduced unpredictable delays and jitter, making it impossible to meet strict performance requirements. The client needed a bare-metal solution with deterministic performance.
Our Solution
We engineered a bare-metal system with custom kernel optimizations
Kernel Optimization
Implemented custom kernel patches removing unnecessary features and optimizing scheduler, memory management, and interrupt handling.
NUMA-Aware Allocation
Built NUMA-aware memory allocation ensuring CPU and memory locality for reduced latency and improved cache efficiency.
DPDK Integration
Integrated Intel DPDK for bypassing kernel network stack and achieving line-rate packet processing with minimal overhead.
Real-Time Tuning
Applied real-time kernel patches with PREEMPT_RT for deterministic scheduling and reduced interrupt latency.
