Benchmarks | PcapPlusPlus (original) (raw)

To evaluate the performance of PcapPlusPlus, we employed two benchmarking methods: comparing it to similar libraries and using Google Benchmark to measure key features. This page presents the results of these tests.

Testing environment​

The benchmarks were conducted on the following system configuration:

• Linux Ubuntu 22.04 64-bit running inside WSL2
• g++ 11.4.0
• The host platform is a Windows machine with Intel Core i7-8700 3.2GHz processor and 16GB RAM running Windows 10

Project Comparison​

To compare PcapPlusPlus with other C++ libraries, we used Matias Fontanini's packet-capture-benchmarks project. This benchmark compares PcapPlusPlus with libtins and libpcap.

PcapPlusPlus was only compared to similar C/C++ projects, as libraries written in higher-level languages (such as Python or Java) cannot match the performance of native C++ libraries.

The following versions were used during the benchmark:

• libpcap-dev v1.10.1
• PcapPlusPlus v24.09
• libtins v4.5

Google Benchmark​

Google Benchmark is a library designed for measuring the performance of C++ applications. We utilized it to evaluate several aspects of PcapPlusPlus. The benchmark code can be found in PcapPlusPlus Examples - Google Benchmark.

The benchmark covers the following operations:

• Reading pcap files (BM_PcapFileRead)
• Writing pcap files (BM_PcapFileWrite)
• Packet parsing (BM_PacketCrafting)
• Packet crafting (BM_PacketCrafting)
