What Is the Impact of the Bandwidth Applied for CodeArts PerfTest on the Test?

The required bandwidth depends on the request and response models of a pressure test. For example, if the TPS is 5000 and each request packet is 1 KB, the total uplink bandwidth is 5000 KB. We can use the same method to estimate the downlink bandwidth. The bandwidth limit only restricts the uplink bandwidth. Therefore, requests with bodies, such as POST and PUT, will consume more bandwidth resources.

If the bandwidth is insufficient during the pressure test, network packet loss occurs. The test report shows a higher latency and occurrence of timeout.
