blockpilabs-hypernode-polygon-stresstest

Tasks

Task 1

Test one (during the first 15 mins):

• Test one is to send simple requests with gradually increased virtual users. Choose the methods below. You can decide the request combination and the request order. Then follow the 3×5 mins VU rules to send requests to the BlockPI network. Save the resulting output of the load testing tool at the end. Check out the k6 docs to specify different VUs at different time https://k6.io/docs/test-types/soak-testing.

• Methods: eth_getTransactionBy*******, eth_blockNumber, eth_getTransactionByBlockNumberAndIndex

3×5 mins VU rules:

• First 5 minutes: 500 virtual users.
• Second 5 minutes: 1000 virtual users.
• Third 5 minutes: 2000 virtual users.

Task 2

Test two (during the second 15 mins):

Test two is to send requests to interact with a dapp contract. Write a script to get the token price with "getAmountsOut" method. Then follow the 3×5 mins VU rules to send requests to the BlockPI network. Save the resulting output of the load testing tool at the end.

3×5 mins VU rules:

• First 5 minutes: 500 virtual users.
• Second 5 minutes: 1000 virtual users.
• Third 5 minutes: 2000 virtual users.

Tool for stress test

For stress-test we use https://k6.io/

Install k6

sudo mkdir .gnupg/
sudo gpg --no-default-keyring --keyring /usr/share/keyrings/k6-archive-keyring.gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys C5AD17C747E3415A3642D57D77C6C491D6AC1D69
echo "deb [signed-by=/usr/share/keyrings/k6-archive-keyring.gpg] https://dl.k6.io/deb stable main" | sudo tee /etc/apt/sources.list.d/k6.list
sudo apt-get update
sudo apt-get install k6

NOTE: If you faced an issue with max file open

Increase file limit

sudo bash -c "cat >/etc/security/limits.d/90-blockpi-nofiles.conf <<EOF
# Increase process file descriptor count limit
* - nofile 1000000
EOF"

Close all open sessions (log out then, in again)

Run test script

k6 run bp-stress-stage-1-random.js
