What's New in ASP.NET Web Pages 3.2
====================
by [Microsoft](https://github.com/microsoft)

This topic describes what's new for ASP.NET Web Pages 3.2, Web Pages 3.2.2 and [Web Pages 3.2.3 beta1](https://blogs.msdn.com/b/webdev/archive/2014/12/17/asp-net-mvc-5-2-3-web-pages-5-2-3-and-web-api-5-2-3-beta-releases.aspx)

## ASP.NET Web Pages 3.2

This release fixes a bug and introduces one new feature.

## Download

The runtime features are released as NuGet packages on the NuGet gallery. All the runtime packages follow the [Semantic Versioning](http://semver.org/) specification. The ASP.NET Web Pages 3.2 package has the following version: “3.2.0”. You can install or update these packages through [NuGet](http://www.nuget.org/packages/Microsoft.AspNet.WebPages/). The release also includes corresponding localized packages on NuGet.

You can install or update to the released NuGet packages by using the NuGet Package Manager Console:

## New Feature and Bug Fix

We fixed one bug and made one minor feature enhancement in this release. You can find the query for the same [here](https://aspnetwebstack.codeplex.com/workitem/list/advanced?keyword=&status=Closed&type=All&priority=All&release=v5.2%20RC|v5.2%20RTM&assignedTo=All&component=Web%20Pages%2FRazor&sortField=Id&sortDirection=Descending&page=0&reasonClosed=Fixed).

## ASP.NET Web Pages 3.2.2

This release rolls-up the change in the [ASP.NET Web Pages 3.2.1 Beta release](https://blogs.msdn.com/b/webdev/archive/2014/07/28/announcing-the-beta-release-of-web-pages-3-2-1.aspx) which provides a significant performance improvement in rendering large razor pages. See[Codeplex Issue 585](https://aspnetwebstack.codeplex.com/workitem/585). This release aligns with the MVC 5.2.2 packages which will now depend on this version.

We worked with the MSN team on rendering large pages. When pages render over 80 Kilobytes of data, we end up with objects on the large object heap. When multiple layers of layouts are used this effect can be multiplied.

The result on the server is extra CPU usage, longer retention of memory, and even long pauses during [Gen 2 cleanup](https://msdn.microsoft.com/en-us/library/ms973837.aspx) in the garbage collector.

Below is a table demonstrating the results of analyzing a [perfview](https://channel9.msdn.com/Series/PerfView-Tutorial) for a run. The CPU is held constant at about 68%, while large pages are being rendered. The table shows that the number of Generation 2 collections has been almost completely eliminated, and the result is higher request rate and a considerable reduction in pauses due to garbage collection.
