VC++ Performance Improvements in VS 2008 A couple of weeks ago I blogged about the performance improvements in Visual Studio 2008.
In
response to that, several of you asked me for more information on how
these types of enhancements had been incorporated into Visual C++.
Though the performance improvements blog highlighted work the Visual C++ team had done around file-level parallel builds and incremental builds for mixed native-managed projects, there are other things in for VC++ in VS 2008 that I thought would be worth mentioning. So, here we go:
· Editor
responsiveness – Updating IntelliSense, displaying the QuickInfo
tooltip and processing AutoComplete requests won’t degrade editor
experience.
· Goto
Definition improvements – Significant reduction in the time required to
“Goto Definitionâ€. One customer reported that a 2 minute delay dropped
to 10-20 seconds.
· Load
solution performance – Load time of large Visual C++ solutions is much
better. Some customers are reporting speed ups of 25%-70%.
· File
lookup in projects – Provides improvements to several scenarios such as
adding files to projects, changing configurations, etc.
· Changing
configuration options – Modifying options, such as adding an include
directory or changing the active configuration, are much faster for
large solutions.
· Reduced
CPU consumption – We now process low-priority background items (such as
IntelliSense population) using 20% less CPU time.
I
do hope that all this work will provide a much enhanced IDE experience
for C++ developers. The Visual C++ team is already hard at work on the
next major version of Visual C++ and is hoping to address even more
performance and scalability issues in the future. Also, for those of
you working on Visual C++ 2005, the team will be releasing a patch that
applies the fixes described above to that version as well.
Namaste!
