    Most SEC Rule 15c3-5 pre-trade risk controls implemented in software incur 2 to 5 µs of OS thread scheduling jitter and kernel context-switching latency. During market micro-bursts, this tail variance leads directly to adverse execution selection and fill slippage.

    We built an immutable FPGA appliance substrate for AWS EC2 (ami-06e581f3a6d6c3e32, targeting Xilinx UltraScale+ silicon) that pins risk-gate state validation directly to physical PCIe MMIO registers.

    Empirical telemetry logged directly on the AWS F2 substrate:

    * Direct PCIe TLP Non-Posted Read (BAR2): 1.220 µs P50 | 1.231 µs P99 (11 ns tail jitter spread)

    * Bare-Metal Kernel-Bypass Logic: 240 ns P50 | 251 ns P99 | 380 ns P99.9

    * Multi-Channel Saturated Line Rate: 14.95M ops/sec across 16 pinned channels

    * Local Zero-Copy Binary Socket IPC (/tmp/oikonomia.sock): 19.77 µs

    * Core Power & Dissipation: 18.2W at 42.5°C nominal core temp

    The public repository contains our synthetic benchmark harness, terminal outputs, and the 1-page institutional diligence memo: https://github.com/joeiko3424-svg/oikonomia-benchmarks

    Curious how other low-latency and systems engineers here are handling hypervisor-induced jitter and memory-bus contention when deploying trading or risk infrastructure in public cloud environments.

      OS thread scheduling jitter and kernel context-switching latency

      This goes away with isolcpus. Have you tried that?
