# Benchmarking
To test the performance of Eclipse Testnet, you can run our benchmarking script. The following test benchmarks AMM swaps to assess the TPS of Eclipse Testnet.
## Prerequisites[](https://icarus131.github.io/devcookbook/docs/Benchmarking#pre-requisites)
* [node.js](https://nodejs.org/en/download/)
* [git](https://git-scm.com/downloads)
Once you have the above installed, clone the benchmarking repository:
```bash
git clone https://github.com/Eclipse-Laboratories-Inc/eclipse-benchmarking/
```
## Running Benchmarking Test[](https://icarus131.github.io/devcookbook/docs/Benchmarking#running-the-benchmarking-tests)
Navigate to the `token_swap` folder after cloning the repository. Install ts-node by running the following command:
```bash
npm i -g ts-node
```
{% hint style="warning" %}
You might have to give super user or admin permissions to install globally or use the `-g` flag.
{% endhint %}
To install the dependencies, run the following command:
```bash
npm i
```
Make sure to run this command inside the `token_swap` folder. The final step is to run the benchmarking tests using the following command:
```bash
ts-node spam.ts
```
This runs 10 instances of an AMM performing any specified number of swaps.
## Modifying Benchmarking[](https://icarus131.github.io/devcookbook/docs/Benchmarking#modifying-the-benchmarking-tests)
The default test is 275 swaps. To modify the number of swaps, modify line 63 in the `benchmark.ts` file inside the `token_swap` folder. The following is the code snippet to modify:
```javascript
...
await mintTo(connection, payer, mintA, userAccountA, owner, SWAP_AMOUNT_IN);
console.log("Run test: benchmark swap");
await benchmarkSwap(275);
console.log("Success\n");
```
If you've followed the steps successfully, you should see an output similar to the following:
