Definition 15.4 Low-Latency Software · Hoofdstuk 15 — Protocols I: FIX

Parsing and building FIX execution reports of about 205 bytes (1 000 distinct messages, median of 40 passes). Measured on a laptop (Intel Core Ultra 7 155H) under WSL2, no isolated cores; C++ with GCC 11 at -O2, Python 3.10. Data: bench_fix.py.
