Welcome to the Hyperledger Caliper project. Caliper is a blockchain performance benchmark framework, which allows users to test different blockchain solutions with predefined use cases, and get a set of performance test results.

Currently supported blockchain solutions:

• Hyperledger Besu, utilizing the Ethereum adapter.
• Hyperledger Fabric v1.X, v2.X
• Ethereum
• FISCO BCOS

Currently supported performance indicators:

• Success rate
• Transaction/Read throughput
• Transaction/Read latency (minimum, maximum, average)
• Resource consumption (CPU, Memory, Network IO, ...)

See the PSWG white paper to find out the definitions and corresponding measurement methods.

For more information on using Caliper, please consult the documentation site
