# zenoh-bench

## Overview

simple benchmark to investigate low latency mode.

## Install & run

1) clone repo 

2) cd zenoh-bench

3) run sub first:  ```cargo run --bin sub```

4) run pub next:  ```cargo run --bin pub```

5) When pub finishes, est. throughput will be printed out

Files:

* Configuration: [src/lib.rs](src/lib.rs)

* Publisher [src/bin/pub](src/bin/pub/main.rs)

* Subscriber: [src/bin/sub](src/bin/sub/main.rs)

Both, pub and sub share the exact same configuration.

## Observations

General:

* Default config gives good performance

* Release build is nearly twice as fast as debug build due to aggressive optimization. See cargo.toml 

Low latency mode:

* Best throughput when enabled

* With publisher in low latency mode, throughput drops in half

* With pub & sub in low latency mode, throughput drops fivefold (from 500k to ~100k).

## Sample measurement

System:

* Apple Macbook, M1

* Mac OS Sonoma 14.1

* rustc 1.74.0 (79e9716c9 2023-11-13)

* zenoh v0.10.0-rc

Release mode with low latency DISABLED:

Max Messages: 1000000 (1 Million)

Elapsed time: 2.338041208s

Throughput: 500000.00 msg/s

```

Release mode with low latency PUB & SUB ENABLED:

```

Elapsed time: 9.321751834s

Throughput: 111111.11 msg/s
