CoreDNS Performance Test Report

Test Background

Latency data of CoreDNS in a standard environment.

Benchmark

This article is based on the environment installed with DCE 5.0, where one group of environments only installed CoreDNS, and another group installed CoreDNS and nodelocaldns, with the remaining parameters set to default configuration.

Physical Machine

Name CPU CPU MEM Network
Node 1 Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40GHz 56C 128G 10G Mellanox
Node 2 Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40GHz 56C 128G 10G Mellanox

The following are the data obtained from load testing on physical servers:

  • With nodelocaldns
