它是明智的构建服务器上使用一个ramdisk？ [英] Is it sensible to use a ramdisk on a build server?

问题描述

在我的公司，我们目前正在研究各种战略加快我们的CI构建。我们已经异形我们构建并决定了我们通过一个I / O瓶颈的制约。我们有相当多的选项，以处理这种在不久的将来（〜1-2个月），但真的想看到改善的现在的

At my company we are currently researching various strategies for speeding up our CI builds. We have profiled our builds and determined that we are constrained by an I/O bottleneck. We have quite a few options to deal with that in the near future (~1-2 months) but would really like to see an improvement now.

我提出了使用RAMDISK作为结算和构建文件位置。生成输出和原木当然会被存储物理磁盘上。

I proposed using a ramdisk as the checkout and buildfile location. The build outputs and logs would of course be stored on physical disk.

是一个明智的做法还是有显著的缺点这种方法？我不是在寻找这方面的东西在硬件方面，但答案，而不是如通用构建系统（如MSBuild的）和虚拟盘之间的相互作用会引起任何问题，如果有其它的风险，我需要知道的。

Is that a sensible thing to do or are there significant drawbacks to this approach? I am not looking for answers that regard the hardware side of things but rather than if the interaction between common build systems (e.g. MSBuild) and a ramdisk will cause any issues and if there are other risks I need to be aware of.

推荐答案

只要你有足够的内存，这是做了非常明智的事情。

As long as you have enough memory, it's a very sensible thing to do.

的唯一缺点是，当然，您的构建丢失在关机/电源故障通常不是为CI一个大问题的基础之上。

The only real drawback is, naturally, your build gets lost on shutdown/power failure which usually isn't a big concern for the CI builds.
