How Ideco Measures NGFW Performance Using TRex ASTF and RFC 9411 Methodology

Ideco engineers have published a detailed methodology for benchmarking the performance of their Ideco NGFW Novum product on the Ideco EX hardware platform. The team uses TRex in Advanced Stateful mode to generate realistic L4-L7 traffic and follows RFC 9411 guidelines to ensure reproducible results across different test environments. Key metrics include throughput on UDP 1518-byte frames reaching 200 Gbit/s, TCP/HTTP performance varying from 100 Gbit/s down to 62 Gbit/s depending on object size, and EMIX mixed traffic dropping from 92 Gbit/s with firewall only to 15.5 Gbit/s when all inspection engines are enabled. The methodology incorporates binary search for maximum load, a 1% session drop threshold, and 300-second hold times per test point to capture real-world behavior rather than short-term peaks. All tests were performed without TLS decryption, with separate plans for hardware-based Keysight BreakingPoint testing when decryption is required. The full article includes hardware specifications, traffic profiles, loss calculation formulas, and configuration details to allow anyone to reproduce the measurements.
