Network stress testing
This guide assumes that:
- You have a working Credit Smart ChaiChainnetwork up and running
- Both your JSON-RPC and GRPC endpoints are reachable
The Credit Smart Chain Loadbot is a helper utility that is meant to stress test a Credit Smart Chain network.
Currently, it supports 2 modes:
transfer- mode that does stress testing using fund-transfer transactions. [Default].
deploy- mode that deploys specified smart contracts with each transaction.
The transfer mode assumes that there is a sender account that has initial funds to conduct the loadbot run.
The sender's account address and private key need to be set in the environment variables:
This section covers some basic terminology regarding the loadbot configuration.
- count - The number of transactions to be submitted in the specified mode
- tps - The number of transactions that should be submitted to the node per second
As an example, here is a valid command you can use to run the loadbot using two premined accounts:
polygon-edge loadbot --jsonrpc http://127.0.0.1:10002 --grpc-address 127.0.0.1:10000 --sender 0x9A2E59d06899a383ef47C1Ec265317986D026055 --count 2000 --value 0x100 --tps 100
You should get a result similar to this on your terminal :
Transactions submitted = 2000
Transactions failed = 0
[TURN AROUND DATA]
Average transaction turn around = 3.490800s
Fastest transaction turn around = 2.002320s
Slowest transaction turn around = 5.006770s
Total loadbot execution time = 24.009350s
