> Recently, I stress-tested a Quorum network consisting of 2 nodes on separate machines, and the result was 140 tps…

So, let’s see how to create a 2 node Quorum network in just a few minutes so that you can also stress-test your own Quorum network. But if you are new to Quorum, I suggest you **_go through the below article_**, to get a better understanding of this article.

[**Quorum 101: Getting started with Quorum**  
_This post marks the first in a new Quorum series I am starting in an effort to provide some easy to read instructions…_medium.com](https://medium.com/@vaibhavsaini_67863/quorum-101-getting-started-with-quorum-9906294ea45b "https://medium.com/@vaibhavsaini_67863/quorum-101-getting-started-with-quorum-9906294ea45b")[](https://medium.com/@vaibhavsaini_67863/quorum-101-getting-started-with-quorum-9906294ea45b)

If you are all set, then let’s get started.

### Environment Used

I am using 2 separate AWS machines (**Ubuntu Server 16.04 LTS, t2-micro**) for 2 separate Quorum nodes. Let us call them `quorum-peer-1` and `quorum-peer-2`.

![](https://hackernoon.com/hn-images/1*7tEK7YYgKVoQvWO7xGmyqA.png)

2 nodes on AWS

Now, if you are running 2 nodes as above then let’s assume IP address of `quorum-peer-1` is `IP-1` and IP address of `quorum-peer-2` is `IP-2`.

Also, open the following ports in the security group(it’s better to use same security group for both the nodes).

_Ports to open_(**all TCP ports ,accessible from anywhere**):

*   9001
*   9004
*   21000
*   21003
*   22000
*   22003
*   50401
*   50404

### Installing prerequisites

Now, we have to install prerequisites on both the nodes(better option is to use a snapshot and use that for installing prerequisites on both the machines). To install the prerequisites just copy and run the below script on both the machines.

### Installing the Quorum application

Now ssh into the `quorum-peer-1` and clone the below repository.

git clone [https://github.com/vasa-develop/quorum-testnode-1](https://github.com/vasa-develop/quorum-testnode-1);  
cd quorum-testnode-1

Similarly, ssh into `quorum-peer-2` and clone the below repository.

git clone [https://github.com/vasa-develop/quorum-testnode-2](https://github.com/vasa-develop/quorum-testnode-2);  
cd quorum-testnode-2

And Voila, you are set to test the network.

### Initializing network

Now execute the below command on both of the machines simultaneously as a **_super user_** (using `sudo su`).

./start-peer.sh <IP-1> <IP-2>; tail -f qdata/logs/constellation\*.log

for example if `IP-1` is 12.45.78.55 and `IP-2` is 12.45.78.56, then the above command will be like

./start-peer.sh 12.45.78.55 12.45.78.56;   
tail -f qdata/logs/constellation\*.log

> Make sure that the IP’s are in correct order, or the script will not work as expected

You will see output similar to below ones.

quorum-peer-1 output

quorum-peer-2 output

If you encounter some error then execute `./stop.sh` and again repeat the “Initializing network” step.

Press CTRL+C to exit the logs.

### Testing the Network

Now, it’s time to test our network. In the `quorum-peer-1` execute the below command

./runscript.sh script1.js

Now, go to `quorum-peer-2` and execute the below command

python3 tps.py

You will see output like the below one

![](https://hackernoon.com/hn-images/1*PBg6x6d6D46A0FCn9zQ3Ig.png)

quorum-peer-2 output

Now, here is the last command to measure the **_TPS._** Execute the below command to start bombarding private transactions from `quorum-peer-1` to `quorum-peer-2` . Execute the following command in `quorum-peer-1` and you will see output similar to screens shown below.

python3 send.py

quorum-peer-1 transaction bombarding

quorum-peer-2 tps results

> Now as you can see, in the above screen that for **first 1000 trxs the average tps rate is around 140 tps.**

Well, that’s better than many blockchains, but not really mind blowing.

when you go for 1000 tps but end up with 140 tps…

Well, that was it…your first Quorum network stress-test. **_If you made it to the end then comment you TPS below_** using different machine sizes. Let’s see how high it can go.
