Visual Studio 2008 Performance Improvements

In the VS 2008, we have made some good strides in improving performance for some of the common scenarios that developers care about.  We set explicit performance goals both for new product features and for improving the performance of existing features. 

For example, with the new LINQ facility we set a goal that LINQ performance be significantly better than using a SqlDataAdaptor for the same query and competitive with using a SqlDataReader, the lightest weight interface available for retrieving data from SQL Server.  In our testing, LINQ does in fact out-perform SqlDataAdaptor on almost every test case we tried, and in many of the exceptions, it is no more than 10% slower than using a SqlDataReader to accomplish the same task.  Given the power of LINQ, we feel this is a very reasonable trade-off.

Some of the more prominent performance improvements in Visual Studio 2008 that we see include:

Rebuilding a Visual Basic project and running a background compiler is 3x faster and uses 3x less memory.  More about this topic here.

·         Scrolling large C# files in the Editor is 100% faster, while typing in new text is 50% faster

·         The response time of IntelliSense with large types in C# is up to 10 times faster

·         Incremental build time runs up to 90% faster on C++/CLI project solutions. More about this topic here.

·          Office Word and Excel files are processed 20x faster on the server

·         TFS Version Control command processing was re-written to support unlimited sized operations on key commands without being memory bound on the server. In our measurements, key Commands also run 10% – 60% faster, with the larger improvements associated with bigger projects.  More about the work to improve TFS scalability here and here.
