💡 In the quant world, tweaking a few sysctl params can cost hundreds of thousands; custom kernel tuning is black magic most can't do.

Network Acceleration

eBPF XDP Mellanox VMA Solarflare/Xilinx/AMD Onload DPDK

Core Optimizations

🚀 Real-Time Scheduling

PREEMPT_RT patches, 1000Hz timer, NO_HZ_FULL tickless, CPU isolation and pinning for deterministic latency.

⚡ Network Stack Tuning

Disabled TCP delays and Nagle, enabled busy polling, jumbo frames support, RSS/RPS multi-queue scaling.

🔧 Memory Subsystem

Transparent Huge Pages (THP), NUMA-aware allocation, disabled compaction and swap, locked critical pages.

🛡️ Security-Performance Balance

Disabled Spectre/Meltdown mitigations, no audit logging, reduced attack surface while keeping core hardening.

Frequently Asked Questions

What is QuantKernel?
QuantKernel is an ultra-low latency Linux kernel optimized for high-frequency trading (HFT). Based on Linux 6.12 LTS, it achieves microsecond-level latency through scheduler optimization, PREEMPT_RT patches, and disabling unnecessary security mitigations.
What latency can I expect?
Average latency <10μs, P99.9 latency <50μs — approximately 5x improvement over stock kernels. With Mellanox VMA or eBPF XDP, sub-microsecond latency is achievable.
What network acceleration is supported?
Built-in support for eBPF XDP, Mellanox VMA, Solarflare/Xilinx/AMD Onload, and DPDK. Recommended with Mellanox ConnectX-5/6/7 or Intel X710/E810 NICs.
Is QuantKernel free?
Yes, completely free and open source under GPL-2.0. Source code is on GitHub. Contributions welcome.
What hardware is recommended?
Intel Xeon Gold/Platinum or AMD EPYC with TSC. Mellanox ConnectX-5/6/7 or Intel X710/E810 NICs. BIOS: disable C-States, P-States, and optionally hyperthreading.
How do I switch back to the stock kernel?
GRUB is configured with a 30-second timeout. On reboot, select "Advanced options" from the GRUB menu to choose the original kernel.
