Anyone tried this? Does it produce faster code than Visual Studio 2008 C++ Express ?
thanks

Re: Visual Studio 2010 C++ Express Beta
The Express versions don't do PGO, which you need for really good performance.
I heard VC++ 2010 betas were buggy so I haven't tried it yet.

Beta 1 was very buggy.jdart wrote: I heard VC++ 2010 betas were buggy so I haven't tried it yet.
Beta2 works fine and is a big improvement over VS2005 (I skipped VS2008).
I'm using the 'premium' beta, not express, which does do PGO and has a profiler included.

Re: Visual Studio 2010 C++ Express Beta
I installed Visual Strudio 2010 C++ Express, and in testing my program, it ran about 1.4% faster. Note my program is mostly 32 bi, this was a Win32 compile on Windows XP, and running on an Atom processor notebook.keinrath wrote:Anyone tried this?

Install was the typical annoying Microsoft. After downloading 200 mbytes of stuff, it instal some, then required a reboot, then installed more, then required a second reboot then finished the install. Expect to take about 45 minutes or so to do this.
Your mileage will vary

Why not try the Microsoft Visual Studio 2010 Premium Beta 2 version

OK, I tried that. Took nearly three hours to install. I get just under a 2% speedup using PGO. But I am not expert on how to refine PGO (how long should the instrument run be?).jarkkop wrote:Why not try the Microsoft Visual Studio 2010 Premium Beta 2 version

Re: Visual Studio 2010 C++ Express Beta
The instrument run has be long enough to hit a representative sample of your code. I use 3 test positions run for 3 minutes each. That gets enough depth that the multithreading and other depth-dependent code is starting to run. Not sure that's optimal but it works well for me.
