测试显示 Retbleed 补丁造成性能下降高达 70%
2022-09-13 11:54 by 绿光
Retbleed 是最近公布的 CPU 预测执行漏洞攻击，影响 ARM、英特尔和 AMD CPU。Linux 内核最近开始加入相关的修复补丁。VMware 工程师在 Linux 5.19 上测试了补丁，结果显示它导致了巨大的性能开销。在 ESX 上运行 Linux 虚拟机，使用单个 vCPU 时，计算性能下降最高 70% ，网络性能下降 30%，存储性能下降最高 13%。关闭补丁之后性能恢复到 Linux 5.18 的水平。如此巨大的性能开销会对应用性能产生影响。VMware 工程师是在英特尔 Skylake CPU 上进行的测试，较新的 CPU 解决了大部分相关问题。
