In general, it all sounds good.

However, VC++ 2005 is seriously lacking in standard compliance. Can I expect any serious improvements? Specifically:

1) Two-phase name lookup

2) Exception specifications

3))Export *

* While many may not like it, it is part of the standard.

I'm using VS2008 beta2. I found that if I double click on a lNK2001 or C1083 error message in the output window, VS hangs for a while before it finds the file.

Steps to reproduce:

Yes, Linker errors which are not linked to a specific file in the project could exhibit this behavior while the IDE tries to find the file (that does not exist) in your project. I can imagine that this could take a long time if you have large solutions. It's not something that we fixed in VS2008, unfortunately. Thanks for bringing it to our attention.

I'm not sure why you should be getting this for C1083 if it's related to an existing source file, though. Perhaps this was about a compiler-generated file? If so, we would definitely be interested in the "steps to reproduce" that you missed above.

Thanks,

Any information on speed improvements in generated code would be helpful.

Microsoft has too many disasters on his hands to be worried about fixing exception handling and export, both of which are broken in the standard itself. If these features were simple and reliable to implement, were in widespread use or even remotely useful then it would be worthwhile. However, none are the case.

>>One customer reported that a 2 minute delay dropped to 10-20 seconds.

Here is what I'm wondering. Let's say there are a million symbols in the database. Let's assume the database is in a binary tree, and every node requires one disk access. This means there will be 20 reads, at 10 milliseconds each. Worst case scenario: 200 milliseconds. Hard to do worse than that, theoretically at least. Now, how can you guys possibly spend 10-20 seconds looking ANYTHING up? Please tell us. I really, honestly, truly don't understand how a lookup could take this long.

I'm very happy with your promise that the performance improvements will be rolled into 2005. It makes it easier to justify buying 2008 knowing that I'm buying it for features not for bug fixes. Thanks.

Can you provide any speed of code execution tests and/or executable file size of VS 2008 versus VS 2005?

We have lots of c++ code that would greatly benefit from even a 5% code execution speedup.

Bob: Do some code profiling and possibly learn some assembly language. You can often get much more than 5% speedup in sections of code if you see what kind of code the compiler is generating, and "assist" it yourself (ie: loop invariant code hoisting, etc.).

I saw _NO_ performance difference in our large (700k+ lines) app between the 2005 & 2008 release builds. But you also can look into things like PGO and LTCG to speed up your executables.

Oh, and don't forget that multi-core is going mainstream, so you may be able to get some help there too.

VC++ in VS 2008 hangs. It is extremely harmful in case files were not saved properly. I'm working with boost and VS 2008. I also observed hangs on VS 2005 after patching. :-(

Timur,

Can you please send some detailed information about the hangs you're seeing to devperf@Microsoft.com, or post a connect bug with details so that we can reproduce and track the issue?

Thanks,

I also really wonder about the 10-20 seconds to look something up.

It's like spending 1 million years to look up a person's phone number in a 2 page phone-book.

It's absolutely mind-boggling...

Patrick,

I'm not sure where you're seeing 10-20 seconds to look something up, feel free to clarify it with me (DevPerf@Microsoft.com).

We do know we have room for improvement with Help and Intellisense, and we're actively working to see what we can do about it in Visual Studio 2010.

Regards,
