标准型 SA3 实例采用最新一代 AMD EPYC™ 处理器的实例，提供多种规格，具有超高性价比。此实例提供了平衡的计算、存储、网络资源，是众多应用程序的最佳选择。
其实例采用 AMD EPYC™ Milan 全新处理器，内存采用最新 DDR4，默认网络优化，最高内网收发能力达1900万pps，最高内网带宽可支持100Gbps。
本次测试的服务器为SA3.MEDIUM4，vCPU及内存为2C4G，未安装BBR等加速内核，完整配置见腾讯云官网的 产品介绍页
Bench.sh 测试
Bench.sh 可以查看 Linux 系统信息，还可以测试网络带宽及硬盘读写速率 由于是国内服务器，所以不对网络进行测试了，这里放出系统信息和硬盘速率

作为对比，上海地区轻量的得分为单核1478.6，多核2666.8，SA3依然更胜一筹
总结
SA3 作为采用最新一代 AMD EPYC™ 处理器的实例，绝不仅仅是一个“大号轻量”，对比轻量应用服务器更能胜任需要运算性能的环境，但相应的价格也会更高。针对不同的使用环境来选择依然是亘古不变的道理。
如果是你，你会选择SA3还是其他厂家的产品呢
