Why C++ is faster than C# for .NET apps

[Tim Anderson]

I interviewed Craig Symonds, general manager of the Visual Studio product
team:

(click the link to Performance issues). It's to do with optimization: in
essence, the C++ compiler will optimize, while C# and VB leave optimization
to the runtime JIT compiler. So not all .NET compilers are "the same", which
is worth bearing in mind.

There is no such link but the questions are right in the interview, so
never mind. Great interview, thanks! I'm disappointed to hear
that C# 2.0 still won't do any optimzation worth speaking of, though.

One thing I would have liked to know: how will the VS 2005 editions
fit in the various MSDN subscriptions? Will Team System come with
MSDN Professional? If it doesn't, and the Express products are as
ridiculously cheap as Symonds speculated, I think I'll won't renew my
Pro sub and just get the Express editions I need. NAnt, NUnit & co.
should work nicely, thank you very much.

<rant> MSDN subscriptions have become virtually worthless lately.
Just a cheap and virtually feature-free VS 2003 update, no Whidbey, no
Longhorn, instead Visual C++ sans IDE as a free download, and then
announcements for super-cheap Express versions and Avalon as a free
download. Microsoft nicely cheated me out of my money there, and I
don't want to let that happen again. :/

I'm not authority and this is only speculation, as I had the same question,
but I suspect the professional MSDN will receive the professional edition of
VS, perhaps even whatever the equivelent to "enterprise" is. But for
Universal Subscribers, they will likely receive what we know today as
"Enterprise Architect" and will most likely include Team System. If team
System is not included as a part of MSDN Universal, there is a good chance I
won't renew my subscription, as well, as I won't pay an addition $2000 for
it on top of the $2000 subscription since I pay for this out of my own
pocket and earnings, not as a company expense. But MS wants these tools to
be used, they'll be available, I recon, just a matter of what subscription
level.


Thanks,
