Commented Unassigned: Sass and SCSS - High CPU usage on IIS [90]

Hi,

I'm using __Bundle Transformer: Sass and SCSS__ in the bundle config..

```
var core = new StyleBundle("~/Content/css", cdnUrl + "Css.gzip").Include(BundleFiles.Core);
core.Builder = nullBuilder;
core.Transforms.Add(cssTransformer);
core.Transforms.Add(cssMinify);
core.Orderer = nullOrderer;
bundles.Add(core);
```

For some reason every time I refresh the web page IIS starts to take a lot of CPU usage (nearly 90% sometimes)..

Any idea why this is happening? I've check on other issues and blogs and some say that version __1.8.29__ fixed the problem. But I got __1.9.25__ and its still happening..

Thanks for your time.
Comments: Hello, Dirett! In [Bundle Transformer 1.9.81](http://bundletransformer.codeplex.com/releases/view/618390) due to the transition to [libSass](https://github.com/sass/libsass) has been significantly increased performance of BundleTransformer.SassAndScss.
