azure托管的Mac管道，关于如何使其更快目前非常慢的建议，在台式机上运行5分钟，在20点附近的服务器上

问题描述

我有这个管道，效果很好，但是在每次构建时都非常耗时桌面版xcode只需不到5分钟即可构建，而在mac cloud服务器中则只需20分钟
特别是它下载的部分在
中配置和编译本机gem。 “安装宝石和cocoapods脚本”任务在下面
接下来是Fastlane任务：“ run fastlane”
编译部分很慢的地方...
我在寻找技巧和窍门，或者更好地组织我的渠道以加快构建速度

使用缓存更新

我添加了缓存部分，但运行时却出现错误

解决方法

您可以考虑并检查here所示的缓存gem：

variables:
  BUNDLE_PATH: $(Pipeline.Workspace)/.bundle

steps:
- task: Cache@2
  inputs:
    key: 'gems | "$(Agent.OS)" | my.gemspec'
    restoreKeys: | 
      gems | "$(Agent.OS)"
      gems
    path: $(BUNDLE_PATH)
  displayName: Cache gems

- script: bundle install

您可以尝试使用自托管代理而不是Microsoft托管代理。

在Microsoft托管的代理中，每次运行管道时，都会得到一个新鲜的虚拟机。一台虚拟机被丢弃使用。
在自托管代理中，计算机级缓存和配置持续存在从头到尾运行，可以提高速度。

请参阅this document中Microsoft托管代理的功能和限制。如果要安装和使用自托管代理，可以参考this document。
