# goroutine-benchmark
Running concurrent Go routines is an effective way to maximize the performance of multi-core processors. If you have undefined amount of tasks, it’s better to limit number of running go routines with a pool mechanism. However, determining this limit is not straightforward. It usually does not equal to the number of processors and can vary between CPU-related and network-related tasks.
This tool allows you to benchmark your current system to identify the optimal number of go routines. It tests both CPU-related and network-related tasks.
# Installation
## From Binary
You can download the pre-built binaries from the [releases](https://github.com/utkusen/goroutine-benchmark/releases/latest) page and run. For example:
`unzip goroutine-benchmark-linux-amd64.zip`
`./goroutine-benchmark --help`
## From Source
1) Install Go on your system
2) Run: `go install github.com/utkusen/goroutine-benchmark@latest`
# Usage
You can run it with default values
`./goroutine-benchmark`
It will produce a result like:
```
