Benchmark openraft without any actual business.

This benchmark is designed to measure the performance overhead caused by Openraft itself.

The benchmark comes with an in-memory log store, a state machine with no data, and an in-process network that uses function calls to simulate RPC.

Benchmark result

clients put/s ns/op
256 1,014,000 985
64 730,000 1,369
1 70,000 14,273

The benchmark is carried out with varying numbers of clients because:

  • The 1 client benchmark shows the average latency to commit each log.
  • The 64 client benchmark shows the maximum throughput.

The benchmark is conducted with the following settings:

  • No network.
  • In-memory store.
  • A cluster of 3 nodes in a single process on a Mac M1-Max laptop.
  • Request: empty
  • Response: empty

Run it

make bench_cluster_of_3 in repo root folder, or in this folder:

cargo test --test benchmark --release bench_cluster_of_3 -- --ignored --nocapture
