New feature called branchcache

in my test installation of Windows Server 2008 R2 I found today below the "Add Features Wizard" the item: "Branchcache" and I was asking myself if this is based on Velocity CTP 3 or is this an indiviual development??



BranchCache

BranchCache, available on both Windows Server 2008 R2 and Windows 7, enables client computers in a branch office to retrieve content securely and locally, instead of retrieving it from a central office server. Because branch offices are typically connected over slower WAN links, BranchCache reduces WAN traffic, and increases application responsiveness on the client computer.






BranchCache installs the services needed to provide BranchCache client functionality. It also provides BranchCache server support for the HTTP protocol, Hostet Cache, and services other then the BranchCache for network files role service.

Velocity CTP3 Released

Microsoft this week rolled out the next community test version of a distributed cache platform code-named "Velocity" that promises to speed up .NET-based applications.
Velocity CTP3 (Community Technology Preview 3) was published on Tuesday and can be downloaded here. The CTP3 represents pre-beta testing; it's of interest mostly to technical reviewers.

Scott Guthrie announced formally during the Mix09 keynote that Velocity will be shipping with ASP.NET 4.0

Velocity CTP2 seems to have memory leaks

based on a project i found today on codeplex: http://www.codeplex.com/CacheScope Microsoft Velocity CTP2 has memory leaks.

Project Description
Provides a scope to wrap around the velocity caching service. It also handles locks and unlocks so that if an item sis called and should be locked after an itial call the scope can handle this under the covers.Resolves the memory leak problem with cachefactory object.This project resolves a memory leak issue with Velocity CTP2 and also provides a methodology for hanlding locked cached objects through a scope provider.

would be intersting to know if it Microsoft thinks same...

Microsoft Project Code Named “Velocity” CTP2

“Velocity” is a distributed in-memory application cache platform for developing scalable, high-performance applications. “Velocity” can be used to cache any common language runtime (CLR) object and provides access through simple APIs. The key aspects of “Velocity” are distributed cache performance, scalabily, and availability.
