wasm-metering

Utilities for benchmarking and analysis of webassembly engines

Setup

Docker and Python 3.7 should be installed as prerequisites

pipenv shell
pipenv install

Build docker images for wasm engines: bash build_engine_images.sh

Usage

Generate Benchmarking Datasets

python main.py benchmark -c

Do Regression Analysis on a Dataset

python main.py analyse -f /path/to/dataset.json

Supported engines

Wasmi - https://github.com/paritytech/wasmi

Benchmark Wasm Format

Wasm blobs used for benchmarking should conform to a standard environment interface. Currently two host functions are exposed to the wasm runtime:

• inputDataCopy(ptr: u32, offset: u32, length: u32): copy length bytes of input data passed from the host (starting at offset) into memory at ptr
• inputDataSize() -> u32: return the size of input data passed from the host
