BPF-Benchmark is a simple testsuit designed to assess the performance of different userspace eBPF (Berkeley Packet Filter) runtimes.


To effectively utilize BPF-Benchmark, follow these steps:

  1. Install Dependencies: Ensure that clang and llvm are installed on your system. If you are using Debian or Ubuntu, you can easily install these packages by executing the command: sudo apt install clang llvm.
  2. Acquire Runtimes: BPF-Benchmark includes three pre-packaged runtimes: llvm-jit, ebpf, and ubpf. If the provided executables are incompatible with your system, you have the option to manually build these runtimes.
  3. Install Required Dependencies: The toolkit relies on various dependencies, all of which are listed in the requirements.txt file. Install these dependencies to ensure smooth functionality.
  4. Compile BPF Programs: Execute the command make -C bpf_progs to compile the BPF programs.
  5. Run Benchmark: Launch the benchmarking process by running the script.
  6. View Results: The results of the benchmark can be observed directly in the console, or you can find graphical representations in the output folder. Additionally, raw data in JSON format is stored in output/data.json.

Adding a New Test

To include a new test within BPF-Benchmark, adhere to these guidelines:

  1. Create BPF Program: Craft an eBPF program and name it as XXX.bpf.c, placing it in the bpf_progs directory. The program should contain a function named unsigned long long bpf_main(void* mem) as its entry point. Any other functions must be inlined using the __always_inline attribute.
  2. Optional Memory File: You have the choice to create a file named XXX.mem if your eBPF program requires specific memory input during execution.

Included Test Cases

BPF-Benchmark currently incorporates the following BPF code test cases:

  • log2_int.bpf.c
  • memcpy.bpf.c
  • native_wrapper.c
  • prime.bpf.c
  • simple.bpf.c
  • strcmp_fail.bpf.c
  • strcmp_full.bpf.c
  • switch.bpf.c

Select and execute the tests ending with the .bpf extension.

Supported Runtimes

BPF-Benchmark facilitates performance comparison across the following runtimes:

  • bpftime-llvm
  • bpftime-rbpf
  • bpftime-ubpf

These runtimes are involved in the benchmarking process to evaluate their relative efficiencies.
