sub-bench

You can use this bench tool to run against substrate --dev node. No configuration needed!

Having your substrate started in --dev mode with default websockets config, run here

npm install
npx tsc
node dist/index.js

or just if already npm-installed & compiled

node dist/index.js

some configuration

You can change how long will it spam transactions in bench.config.json:

processedTransactions = 1000

replace it with any number to spam more/less

In the same file, you can change how much is spammed per seccond:

tps = 100

websockets url is set in polkadot.bench.config.json

kudos

thanks for @mixbytes and their tank project which actually runs those configured benchmarks
