This is a benchmark application used for measuring PcapPlusPlus performance. It is based on Matias Fontanini's packet-capture-benchmarks project (https://github.com/mfontanini/packet-capture-benchmarks).
See this page for more details: http://seladb.github.io/PcapPlusPlus-Doc/benchmark.html
This application currently compiles on Linux only (where benchmark was running on)
