大的C#编译时间增加了吗? [英] Large C# compile time increase?

问题描述

我维护一个用于构建C#解决方案的构建系统.
该代码库由VS解决方案文件组成，目前在代码库中约有160个组件.
自动构建在使用CruiseControl和NAnt的专用构建服务器上运行，以构建每个构建的整个代码库.

组件之一由大约120个C#项目组成.在开发机器上以及直到最近在构建服务器上，该解决方案的完整重建过程都需要3到4分钟.

大约2周前，在一次构建和一次构建之间，该组件的编译时间跃升至16分钟.没有其他组件显示出类似的构建时间增长.

我们假定这与中间文件挂在某个地方有关，因此我删除了整个AccuRev工作区，然后将其重新填充到构建计算机上.
此组件的构建时间从10个构建(超过4天)减少到3分钟左右，然后又跳回了16分钟.
几天后，我重复删除并重新填充工作区，这次将5次构建的构建时间回落到3分钟，然后又跳回了16分钟.

我已存档日志文件，释放了磁盘空间并整理了硬盘驱动器的碎片.

我有点茫然地解释为什么会这样.
这仅在构建机器上发生，开发人员构建需要3-4分钟.

如果有人对导致像这样的C#解决方案的编译时间急剧增加的内容有任何建议，我将不胜感激.

谢谢，

I maintain a build system for building C# solutions.
The code base is componentized by VS solution files and there are currently about 160 components in the code base.
The automated builds are run on a dedicated build server using CruiseControl and NAnt to build the entire code base each build.

One of the components consists of about 120 C# projects. On development machines and up until recently on the build server a complete rebuild of this solution took between 3 and 4 minutes.

About 2 weeks ago, between one build and the next, the compile time for this component jumped to 16 minutes. No other component exhibited a similar increase in build time.

We assumed this had something to do with intermediate files hanging around somewhere, so I deleted the entire AccuRev workspace and repopulated it on the build machine.
Build times for this component dropped back to around 3 minutes for 10 builds (over 4 days) and then jumped back to 16 minutes.
After a couple of days I repeated the workspace delete and repopulate and the build times dropped back to 3 minutes for 5 builds this time before jumping back to 16 minutes.

I have archived log files, freed up disk space and defragmented the hard drive.

I''m at a bit of a loss to explain why this is happening.
This only occurs on the build machine, developer builds take 3-4 minutes.

If anyone has any tips on what might be causing a dramatic increase in compile time for a C# solution like this, I''d appreciate hearing them.

Thanks,
