[smart-bench](https://github.com/paritytech/smart-bench): Weight based

[schlau](https://github.com/ascjones/schlau): Time based benchmarks to
compare performance
The FRAME development environment provides modules (called "pallets") and support libraries that you can use, modify,
and extend to build the runtime logic to suit the needs of your blockchain.
