我一直在一台 5 年前的 Mac Mini 上使用 Ruby on Rails 开发动态网站，它一直很棒，只是运行我的简单测试套件需要太多时间——大约 15 分钟。我相信，如果升级计算机并运行 ubuntu，我就可以减少这个时间。不过，我不知道瓶颈在哪里导致这些测试运行缓慢。我应该关注 CPU、RAM、硬盘、主板吗？如果我的 CPU/主板具有一些图形功能，我是否还需要显卡？
我读了打造一台出色的 2014 年 PC并研究了逻辑增量。我整理了一个初步版本PC零件挑选器。我正准备发布我的计划构建Reddit 的 Build A PC 网站当我感到胆怯时。我读过的大部分信息都是关于最佳游戏的，但我不确定这是否适合我的需求。
如果有人能就我对最佳 ruby on rails web 开发的需求分享我的见解，我将不胜感激。
提前致谢！Ben
