.NET 4.0 VS 3.5运行时性能 [英] .NET 4.0 vs 3.5 runtime performance

问题描述

现在，VS2010是RC现在看来，这只是个星期，直到2.0以来的第一个新核心运行时释放问题。虽然我没有直接需要升级我不知道是否有人已经做了一些性能测试/两者之间的标杆。

Now that VS2010 is in RC it seems it's only matter of weeks until first new 'core' runtime release since 2.0. Whilst I do not have immediate needs to upgrade I'm wondering if anyone has done some performance testing/benchmarking between the two.

如果有任何明显的性能增益那么这将是有益的重新编译现有，工作，应用

If there are any noticeable performance gains then it would be beneficial to recompile existing, working, applications.

TIA，

推荐答案

我发现.NET 4.0是一个测试套件只是一点点慢，我们跑。测试运行了一堆用System.Data.Sqlite对SQLite数据库的查询，它们运行相比，4.0 .NET 3.5快1-2％。不知道为什么他们更快，但我们在这里谈论毫秒，所以我不是太担心。

I have found .NET 4.0 to be just a tiny bit slower in one test suite we run. The test runs a bunch of queries against a SQLite database using System.Data.Sqlite, and they run 1-2% faster on .NET 3.5 compared to 4.0. Not sure why they are faster, but we are talking about milliseconds here so I'm not too worried.
