Query: Performance Characterization and Bottleneck Analysis of Hyperledger
  Fabric   Hyperledger Fabric is a popular open-source project for deploying
permissioned blockchains. Many performance characteristics of the latest
Hyperledger Fabric, such as performance characteristics of each phase, the
impacts of ordering services, and bottleneck and scalability, are still not
well understood due to the performance complexity of distributed systems. We
conducted a thorough performance evaluation on the first long term support
release of Hyperledger Fabric. We studied the performance characteristics of
each phase, including execute, order, and the validate phase, according to
Hyperledger Fabric new execute-order-validate architecture. We also studied the
ordering services, including Solo, Kafka, and Raft. Our experimental results
showed some findings as follows. 1) The execution phase exhibited a good
scalability under the OR endorsement policy but not with the AND endorsement
policy. 2) We were not able to find a significant performance difference
between the three ordering services. 3) The validate phase was likely to be the
system bottleneck due to the low validation speed of chaincode. Overall, our
work helps to understand and improve Hyperledger Fabric.
