ipc-bench

Some very crude IPC benchmarks.

ping-pong latency benchmarks:

• pipes
• unix domain sockets
• tcp sockets
• eventfd (Linux only; notifications)
• io_uring MSG_RING (Linux only; ring-to-ring messages)

throughput benchmarks:

• pipes
• unix domain sockets
• tcp sockets

Building

Requires a C compiler, CMake 3.10 or newer, and a build tool such as Make or Ninja. On Linux, install the optional liburing development package (version 2.2 or newer) and pkg-config to also build io_uring_lat.

From the repository root:

mkdir -p build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .

Executables are created in the build directory. For example, from that directory, measure pipe latency with 8-byte messages and 100,000 roundtrips:

./pipe_lat 8 100000

On Linux, you can also run:

./eventfd_lat 100000
./io_uring_lat 100000  # if built with liburing
