Catapult LoadTest Scripts

Usage

Create privateKeys.json from addresses.yaml.

Collect privateKeys for creating signed transactions.

cp /path/to/build/generated-addresses/addresses.yaml .
cat addresses.yaml | yq '[.nemesis_addresses[0:20][].private]' > privateKeys.json

Using yq is pretty convenient.

Generate Payloads

Pass number of payloads you want to create.

# go, very faster than nodejs. It is worth to setup go environment!
time go run payloadGenerator.go -f ./privateKeys.json -n 10000 > payloads.txt

# nodejs, 2nd argument means number of payload. Verrrry slow. Not recommended.
time node payloadGenerator.js ./privateKeys.json 10000 > payloads.txt

Execute load test

node loadTest.js ./payload.txt http://localhost:3000

Get block data

node blocks.js http://localhost:3000 > data.csv

You can get data like below.
