latency-audit

Linux Infrastructure Validator

"One misconfigured sysctl cost a trading desk 340μs per trade"

Linux infrastructure validator that audits kernel settings, network tuning, and system configuration for low-latency trading.

  • [x] Swappiness (should be 0)
  • [x] Transparent Hugepages (should be `never`)
  • [x] Kernel preemption model
  • [x] Frequency Governor (should be `performance`)
  • [x] C-States (should be disabled)
  • [x] Core Isolation (`isolcpus` configuration)

latencyscope

eBPF Latency Profiler

"Find the exact syscall adding 50μs to your hot path"

eBPF-based latency profiler that traces system calls, network packets, and scheduling delays at nanosecond resolution.

  • eBPF tracing with <1% overhead
  • No code instrumentation required
  • Percentile breakdowns (p50, p99, p999)
  • Export to flame graphs

Why These Exist

After seeing the same misconfigurations at three different trading firms, I automated the audit process. latency-audit is the tool I wish I had on day one.

latencyscope came from debugging a 47μs spike that only appeared under production load. Traditional profilers added too much overhead. eBPF was the only way.
