DNS Performance on Alibaba ECS Instances
Different instance types have different CPU, RAM and throughput capacity. Latency and throughput testing was performed on the following instances using dnsperf. The results captured after running the test for 1 minute are collected in the following table.
From these statistics, it is recommended to have an instance type having a minimum capability of ecs.c6.xlarge for optimal DNS performance. Refer to the Alibaba Cloud Instance family documentation for information on instance configurations.
| Instance Type | Maximum DNS Throughput |
|---|---|
| ecs.c6.large | 2000 qps |
| ecs.c6.xlarge | 5000 qps |
| ecs.c6.2xlarge | 10000 qps |
| ecs.hfc6.large | 2200 qps |
| ecs.g6e.large | 3000 qps |
