VMware Player VM-1个核心CPU限制 [英] VMware Player VM - 1 core CPU limitation

问题描述

我正在将VM与VMware Player结合使用来编写代码和进行编译. 由于我当前的程序很大，因此编译需要一段时间(最多5分钟) 使用主机上4核CPU的25％= 1核的100％.

I'm using a VM with VMware Player to write code and compile. As my current program is huge, the compilation takes a while to be done (upto 5 minutes) using 25% of my 4 cores CPU on my host = 100% of one core.

VM似乎只能使用1个单核.

It seems that the VM is limited to use 1 single core.

是否有一种方法可以优化VM可以使用的内核数量? 我想使用4核CPU的50％或75％.

Is there a way to optimize the number of cores a VM can use? I'd like to use 50% or 75% of my 4 cores CPU.

谢谢

推荐答案

听起来您受可运行的并行构建任务数量的限制，而不是受VM CPU配置的限制，例如，默认情况下，make一次运行一步.尝试并行运行几个步骤，例如，运行 make -j4 或等同于您的构建系统.

It sounds like you're limited by the number of parallel build tasks you can run, not the VM CPU configuration, e.g., by default, make will run a single step at a time. Try running several steps in parallel, e.g., run make -j4 or equivalent for your build system.

另外，对于您来说，VM给您带来的开销可能比您想要的要多；考虑使用 Docker 托管您的开发环境.

On a separate note, a VM may be more overhead for you than you might like; consider using Docker to host your development environment.
