交易吞吐率throughput和延迟latency的区别

Posted 2021-12-14 软件工程小施同学

• Transaction throughput is the number of transactions that the system can process per second.
• Latency is the time it takes for an application to send a transaction proposal to the transaction commit.

• Throughput – successful transactions per second

• Latency – response time per transaction

• Scalability – the ability to support increasing number of participants.

Transaction throughput represents the number of transactions that can be processed at a fixed time, and latency represents the response and processing time to transactions. In practical applications, two factors need to be comprehensively examined. It is incorrect to consider only transaction throughput without latency. Long-term transaction response will hinder user experience and affect users’ experience. Considering latency without throughput will cause lots of transactions to be queued.
