High CPU caused by TortoiseSVN process TSVNCache.exe

本文介绍如何通过配置TortoiseSVN的TSVNCache.exe来避免其占用过多CPU资源。通过设置排除和包含路径，可以指定扫描范围，减少不必要的系统扫描，从而降低CPU使用率。

Problem:

The TortoiseSVN process "TSVNCache.exe" constantly occupies the CPU.

TSVNCache.exe is one of TortoiseSVN processes running in background and searching for directories on hard drive that are under version control. It often consumes lot of CPU resources and gives machines a hiccup, and it seems like the only way to stop it is to kill it.

Fortunately we can configure TSVNCache to scan places that we know are under version control. Here’s step by step instruction on how to do it:

Right-click on your desktop, from TortoiseSVN menu choose Settings
In tree-view on the left choose Icons Overlays
In Exclude Paths text box type paths on your system that are not under version control ( use wild cards to exclude whole directory trees )
In Include paths enter paths that you know are under version control
Click OK
Open Task manager ( right-click on your taskbar and choose Task Manager ) and kill TSVNCache.exe

Solution:

This is because TortoiseSVN is scanning your entire file system to update its internal cache.

This can be simply fixed by doing the following:

1. Right-click on any folder, and navigate to TortoiseSVN --> Settings --> Icon Overlays

2. Under "Exclude paths", set it to c:\*

3. Under "Include paths", include all folders in which your SVN code exists

An example will help here:

Exclude:
       C:
       C:\develop\?
       C:\develop\tsvn\obj
       C:\develop\tsvn\bin

Include:
       C:\develop
