# Mango bencher - stress solana cluster by simulating mango markets

This project is use to stress a solana cluster like devnet, testnet or local solana cluster by simulating mango markets. This code requires ids.json which describe mango group for a cluster and accounts.json file which has preconfigured user accounts in mango.

The code then will create transaction request (q) requests per seconds for (n) seconds per perp market perp user. Each transaction request will contains remove following instruction CancelAllPerpOrders and two PlacePerpOrder (one for bid and another for ask).

For the best results to avoid limits by quic it is better to fill the argument "identity" of a valid staked validator for the cluster you are testing with.

## Build

Clone repo
```sh
git clone https://github.com/godmodegalactus/mango_bencher
```

Update submodules
```sh
git submodule update --init --recursive
```

Set solana version in deps (replace v1.14.3 with require solana version)
```sh
cd deps/solana && git checkout v1.14.3
```

Build
```sh
cargo build -j8
```

## Run

```sh
cargo run --bin solana-bench-mango -- -u http://localhost:8899 --identity authority.json --accounts accounts-20.json  --mango ids.json --mango-cluster localnet --duration 10 -q 2 --transaction_save_file tlog.csv --block_data_save_file blog.csv
```

help will give following results
