6. Performance Evaluation
- Transaction Response Time: It is the time in which a success is measured by the amount of time a transaction takes to request and get response from a blockchain platform.
- Transaction Throughput: The rate at which a success is measured by valid transactions which are committed by the blockchain system under testing (SUT) in a defined time period.
- Transaction Latency (Min, Max, Average): Time taken for a transaction effect to be used across the network is referred to as transaction latency. The total time includes the time from the point of submission to the available result in the network.
- Resource Utilization: It is a process to utilize resources while processing transaction request and response. Resource utilization can be measured by checking the utilized resources by CPU, Memory, Network, and IO by the blockchain SUT in a defined time period.
