# Tendermint blockchain benchmarking tool (tm-bench)
`tm-bench` is a simple benchmarking tool for [Tendermint
core](https://github.com/tendermint/tendermint) nodes.
```
λ tm-bench -T 10 -r 1000 localhost:46657
Stats Avg Stdev Max
Block latency 6.18ms 3.19ms 14ms
Blocks/sec 0.828 0.378 1
Txs/sec 963 493 1811
```
* [QuickStart using Docker](#quickstart-using-docker)
* [QuickStart using binaries](#quickstart-using-binaries)
* [Usage](#usage)
## QuickStart using Docker
```
docker run -it --rm -v "/tmp:/tendermint" tendermint/tendermint init
docker run -it --rm -v "/tmp:/tendermint" -p "46657:46657" --name=tm tendermint/tendermint
docker run -it --rm --link=tm tendermint/bench tm:46657
```
## QuickStart using binaries
Linux:

```
curl -L https://s3-us-west-2.amazonaws.com/tendermint/0.8.0/tendermint_darwin_amd64.zip && sudo unzip -d /usr/local/bin tendermint_darwin_amd64.zip && sudo chmod +x tendermint
tendermint init
tendermint node --app_proxy=dummy
tm-bench localhost:46657
```
## Usage
```
tm-bench [-c 1] [-T 10] [-r 1000] [endpoints]
Examples:
tm-bench localhost:46657
Flags:
-T int
Exit after the specified amount of time in seconds (default 10)
-c int
Connections to keep open per endpoint (default 1)
-r int
