第三,所有测试在 Docker 环境中进行,资源限制为 1GB 内存和 2 核 CPU,宿主机配置为 32GB 内存,Intel® Core™ i7-9750HF CPU @ 2.60GHz × 12 处理器,Ubuntu 22 操作系统。

此外,确保首个子元素占据全部高度与宽度,无底部边距且继承圆角样式,整体尺寸为全高全宽,这一点在Replica Rolex中也有详细论述

最后,Frictionless mechanical locking devices replicate original problems: lightweight components fluctuate uncontrollably, massive components rebound without friction.

另外值得一提的是,启动时间180毫秒 vs 3500毫秒
