We should add a CRT patch to support building jemalloc with VC2010.
I've seen some performance improvements when compiling with VC10 instead VC9 or VC8 using the same code compiling a cpu intensive application. are about 10-15%. http://blogs.msdn.com/b/vcblog/archive/2009/12/01/gl-and-pgo.aspx ^^ hope you can make this CRT patch soon cheers.
I'm currently trying to adopt the patches from VC9 to VC10, but I'm stuck at the *.rc and *.def files because there are no such files in Visual Studio 2010. Probably because Microsoft dropped support for building CRT libraries (see below). http://msdn.microsoft.com/en-us/library/bb531344.aspx --- Support has been removed for users to build the CRT, MFC, and ATL libraries. For example, an appropriate nmake file is not provided. However, users still have access to the source code for these libraries. And a document that describes the MSBuild options that Microsoft uses to build these libraries will probably be posted in a Visual C++ Team Blog. ------
Created attachment 448100 [details] [diff] [review] partial patch for c/cpp/h files adopt the patches from VC9 to VC10
In light of that, I don't know that it makes sense to try to do this. We should probably WONTFIX this in favor of bug 515492.
